Why Timing Governs Hitting: A First-Order Principle Approach
By Ken Cherryhomes ©2025
Reframing the Hitting Problem
Hitting, at its core, is a spacetime, temporal-spatial, coordination problem. Mechanics matter, but they’re not first in line. Before you can refine how to move, the brain must first solve when. This isn’t philosophical. It’s empirical—backed by decades of developmental research across reaching, locomotion, and object interception. The evidence reveals a consistent order of operations in motor learning: timing stabilizes before mechanical precision emerges.
The implications for baseball are profound. If the hitter mistimes the swing launch, no amount of mechanical polish can save the outcome. The swing is late before the barrel ever moves.
Timing governs the feasibility of success. Mechanics optimize its quality.
Once timing is solved—or at least the constraint is reduced—most motor plans (swing theories) suffice. That’s not theoretical. It’s what the data, the footage, and the physics all agree on. If the bat isn’t launched on time, the rest is irrelevant.
That is why timing comes first. Always.
Mechanical refinement, intent, and spatial optimization all exist downstream of this equation. They are second-order objectives, only actionable once the timing constraint is satisfied. Most current training models reverse this order, attempting to perfect the shape of the swing without securing the one variable that dictates whether the swing can succeed at all.
Pre-locomotor infants begin judging descending ball catchability using time-to-contact rather than distance—before grasp mechanics improve.
→ Perceptual timing matures before coordinated motor output.

Swing mechanics can be taught. Launch angles can be coached. Barrel control can be modeled. But all of these exist after the core constraint of timing is resolved. A mistimed swing cannot be mechanically salvaged. The bat cannot arrive early once it is late.
The toddler does not succeed because of instruction. He succeeds because the task permits no ambiguity: swing at the right time, or miss. Once that problem is solved, the motor system—not a coach—begins to express second-order solutions: trajectory, intent, manipulation.
This is the model the xFactor Hitting System is built on. It does not chase swing theory. It solves for time. Mechanics follow.
A Technician by Training, But a Timing Theorist by Constraint
I’ve spent over 30 years coaching hitters. I understand swing mechanics on a granular level—from Bernstein’s principles of motor learning and degrees of freedom, to ground reaction forces (GRFs), ground force angles (GFAs), and rotational torque transfer across the three-segment kinetic chain. I’ve trained elite hitters, optimized movement patterns, and rebuilt swings from the ground up. I can talk path, posture, plane, and pattern with anyone.
But despite that fluency, I default—by design—toward timing-centric methodology. Why?
Because mechanics, no matter how optimized, are not the constraint. They are a response to the constraint.
Once timing is stabilized, the body self-organizes. I’ve seen it in toddlers. I’ve seen it in professionals. Most hitters—when freed from temporal uncertainty—begin solving second-order objectives on their own. They learn to shape outcomes rather than just survive contact. The nervous system is wired to exploit affordances—but only after it knows when to respond within a perception-action task.
That’s why my technology does not enforce mechanical ideals. The xFactor Hitting System is mechanically agnostic. It does not care whether your swing is rotational or transitional, a naturally arcing path or an engineered launch angle centric path. It does not assume a model. It assumes a task: put the barrel on the ball in time. Everything else is a variation.
The Hitter’s Constraint: A Spacetime Problem
A bat can only occupy one spacetime coordinate at a given instant. The sweet spot does not hover, linger, or track the path of the ball longer based on swing quality or swing theory. That notion is simply untrue.
Because pitch arrival times vary, the hitter must synchronize swing launch and swing duration so that:
t_launch + t_swing = t_ball-contact
Where:
- t_launch is determined by perception and decision latency
- t_swing is the fixed mechanical duration of the batter’s swing
- t_ball-contact is dictated by the pitch’s arrival at the intended point of contact
If t_launch is mistimed—even by milliseconds—no amount of mechanical refinement can place the barrel at the ball’s future coordinate in time. The miss is baked in before the bat even moves.
Why This Matters
Most training systems fixate on form—on the visible arc of movement. But they do so downstream of the problem. I, like my xFactor Hitting System, take the reverse approach: address timing first, provide guided solutions that stabilize swing launch across pitch types and locations. Once timing variance falls below a threshold, mechanical consistency emerges naturally—just like it does in infants learning to reach or catch.
Operationalizing the First-Order Constraint
It’s not enough to name timing as the first-order constraint. You have to do something about it.
That’s where my training methodology—and the design of the xFactor Hitting System—depart from convention. It doesn’t teach around timing. It doesn’t treat it as a natural byproduct of repetition or mechanical instruction. It addresses it head-on: by identifying, isolating, and solving for it.
Step One: Identify the Constraint Using First-Order Principle Analysis
Before anything can be trained, it must be understood. My methodology and that of the xFactor Hitting System begins with a first-order principle analysis of the task itself: what must be true for a swing to result in contact?
The answer is not mechanical. It’s temporal.
Everything hinges on this equation. If launch timing is off, nothing downstream can rescue the swing. That constraint isn’t abstract. It’s structural. It defines the window within which all meaningful movement must occur.
Step Two: Build a Trainable, Mathematical Protocol
Once the constraint is known, the next step is making it trainable. The xFactor system uses a mathematical protocol grounded in behavioral science:
- Cues are used not to simulate game conditions but to guide precise solutions.
- The system eliminates guesswork by presenting the hitter with exact timing references, reducing the cognitive load and allowing faster temporal memory encoding and spatial skill acquisition.
- This approach mirrors errorless learning, enabling batters to encode correct timing through repeated success, not trial and error.
Timing isn’t treated as an innate gift. It’s solved like a math problem—and then trained like a reflex.
And once timing is no longer confounding, mechanics begin to reorganize on their own. Base motor plans, previously locked or rigid, gain fluidity. Degrees of freedom open. Symbiotic couplings reestablish. Movement becomes expressive, not compensatory. The mechanical system doesn’t improve because it was adjusted—it improves because the constraint that restricted it has been removed. This is not instruction. It’s emergence.
Step Three: Capture, Measure, and Quantify All Temporal Components
The final layer is measurement. You don’t just guide timing—you must capture and quantify its component parts first.
The AI SwingPilot™, powered by the Swing Alert™ Engine, provides the timing solutions, while the xFactor Swing Dynamics Pro™ quantifies:
- Swing Delay™ (reaction time plus mechanical lag)
- Time to Impact (TTI) across 25 mapped contact locations, based on the batter’s unique swing arc
- Launch timing relative to pitch trajectory and outcome probability
Time to Impact (TTI) is the duration between swing initiation and the bat’s arrival at a specific contact point. It reflects the purely mechanical phase of the swing—distinct from decision latency. Because the swing arc is three-dimensional, TTI is not fixed; deeper pitches yield shorter TTIs, while forward or inside pitches require longer durations to reach.
What enables this measurement is the system’s proprietary cue methodology, which replicates the constraint. The cue is not a suggestion. It is a proxy for the pitch’s location in space at the moment the hitter must respond. In other words, the system doesn’t let the hitter swing at their convenience. It enforces the same temporal urgency a real pitch demands.
This is how Swing Delay™, mechanical swing time, and TTI are captured: the hitter must react to the cue as if the ball were arriving at the optimal contact point. That response exposes both the perceptual reaction and the mechanical lag that follows it—together forming the measurable total swing time.
Importantly, TTI is not a generalized swing duration. It is mapped across 25 pitch locations—a three-dimensional lattice generated by the batter’s own swing geometry. This contact point map reveals when and where the bat can successfully arrive in time across the zone. It captures not just swing quality, but swing feasibility, making timing corrections location-specific.
This methodology allows for objective diagnostics, not subjective interpretation. Hitters don’t wonder what went wrong. The system tells them—in milliseconds.
And because these values are measurable, repeatable, and spatially tied to pitch contact constraints, this layer doesn’t just evaluate—it enables swing timing training itself. Precision correction is possible only because timing has been fully captured.
It also enables outcome mapping: knowing not just when a swing was launched, but whether that launch intersected with a contact point that aligned with the hitter’s intent—be it elevation, direction, or barrel control.
The Result
You’ve moved hitting out of the realm of folklore and into a domain of solvable precision. Not by rejecting mechanics, but by solving the constraint that governs whether mechanics matter at all.
This isn’t swing theory. It’s constraint resolution.
By identifying the problem (timing), building a trainable solution, and capturing the data that confirms or corrects it, the system closes the loop between theory and execution. But training in isolation isn’t enough. Timing must be solved in real time, pitch to pitch.
That’s where the AI SwingPilot™, powered by the Swing Alert™ Engine, completes the process.
Built on the swing time map created by the xFactor Swing Dynamics Pro™, SwingPilot™ provides precise, individualized timing cues for each pitch scenario. It doesn’t simulate timing. It computes it—by subtracting the batter’s Time to Impact (TTI) from the pitch’s projected arrival time at a defined contact point. The result is a launch signal that tells the hitter when to go—based on their own swing, not a generic model.
Because TTI is mapped across 25 spatial coordinates, the system knows when each segment of the swing arc will intersect a moving pitch. That means the cue isn’t just accurate for “fastballs down the middle”—it’s accurate for any pitch at any location, at any speed or distance.
No recalibration. No mental math. No guessing.
Just a launch cue that adjusts dynamically to:
- Velocity changes
- Pitch location variability
- Distance adjustments
- Desired contact depth for situational hitting
The AI SwingPilot™ doesn’t replace training—it operationalizes it. It takes the individualized data measured in Step Three and converts it into actionable guidance, live and in context. The same data used to evaluate progress is now used to drive it.
The result isn’t just better timing. It’s solved timing.
What Toddlers Can Teach Us About Temporal Priority
To demonstrate the first-order dominance of timing—and the emergent nature of second-order objectives—we offer two visual exhibits: toddlers who, without instruction or biomechanical feedback, not only make contact with pitched balls but do so with outcome-driven intent.
Exhibit A: Solving the First-Order Constraint
But this swing isn’t about mechanics. It’s about timing. He doesn’t react to the ball. He predicts its arrival. He selects an intersection point in space, estimates his own swing time to reach it, and initiates movement accordingly.
He solves the when—and because of that, the how self-organizes. The bat meets the ball because the launch was timed correctly, not because the swing was trained. That’s the whole point. The temporal constraint was solved, and movement fell into place.
This isn’t a display of mechanics. It’s a demonstration of what emerges after the first-order constraint is satisfied. Temporal coordination makes possible the spontaneous organization of second-order movement.
Exhibit B: Second-Order Emergence Through Intent
In the second clip, slowed for clarity, the outcome deepens. Not only does the child make contact, he shapes the result. The barrel path meets the ball with an upward attack angle, producing lift—a purposeful outcome. This isn’t just temporal survival, It’s intent guided spatial control.
The hitter’s goal is no longer just intersection. It’s influence. He transitions from simply making contact with the pitch to the manipulation of its outcome.
Importantly, this second-order control emerges only after the first-order constraint has been satisfied. The child cannot lift what he cannot hit. This is what most swing theorists and coaches miss: mechanical expressiveness is not the foundation of hitting—it is the reward for getting the timing right.
What Coaches and Players Misdiagnose as Mechanical Failure
A lot of hitting coaches will blame a hitter’s lack of success by claiming the batter wasn’t executing the swing they were taught.
And vice versa.
Hitters will often blame the new swing, the new coach, or the instruction itself—believing the mechanics don’t “hold up” under pressure. But in many cases, the problem isn’t the swing design—it’s that the new movement pattern was never reconciled with the timing demands of the live environment.
Here’s what neither side seems to understand:
When timing is unresolved, a visible mechanical breakdown is not disobedience. It’s a reaction. The batter may very well be attempting to apply the trained swing pattern—but the constraint has shifted. When the hitter is confounded by timing, the first-order objective takes over: make contact. The batter’s swing may revert back to older motor patterns, a hybrid of old and new, or something resembling neither.
What happened was the motor system recognized that the trained plan was not viable for the incoming pitch’s temporal profile. The brain reacts—instinctively—by introducing panic and tension, simplifying the motor strategy. This is not abandonment. It is adaptation. And it often takes the form Bernstein described in his stages of motor learning:
- Degrees of freedom are reduced
- Couplings are frozen
- Mechanical variability is suppressed
The hitter reverts to a base-level motor plan—optimized for temporal survival, not mechanical expression. This happens more often than most realize, particularly when hitters undergo swing overhauls under a new coach or swing philosophy.
Here’s the problem: Most swing overhauls are trained in static environments or under low-timing constraint conditions—tee work, slow toss, pattern recognition drills. The hitter appears to master the new movement. But what they’re actually doing is calibrating that movement to a reduced temporal demand.
Then the lights come on. Five o’clock shifts to seven.
The moment timing becomes volatile—pitch speed increases, sequencing becomes unpredictable, or decision latency is taxed—the swing begins to fracture. The hitter is now trying to apply a new movement pattern to a pitch environment that was previously matched to a different internal model.
Even if the pitch velocity hasn’t changed, the old timing solution was calibrated to the old swing’s duration and launch profile. The new swing may have a different Time to Impact, a different path shape, or a different sequence—and unless it’s recalibrated under live timing conditions, it won’t match the event.
The result is a mismatch: the swing arrives too early, too late, or off-plane, not because it’s flawed, but because it was trained under a different temporal demand. The hitter doesn’t fail because they didn’t learn the movement—they fail because they never relearned the timing that movement now requires.
And this is where most coaching breakdowns happen:
The coach sees the swing fall apart and assumes the hitter lost focus or failed to apply instruction. The hitter often agrees, blaming the coach or the new swing. But that failure was triggered upstream—in the launch decision, not in the swing path. The problem wasn’t necessarily mechanical. It may have just been unsolved timing masquerading as an inefficient swing.
Until the timing constraint is resolved, no swing model will hold.
The body will continue to override the plan in service of first-order constraint resolution.
Developmental Validation of Temporal Primacy
Developmental research across motor tasks consistently supports the sequencing you see in hitting:
- Temporal coupling becomes reliable
- Motor redundancy is exploited to reduce spatial error
- Performance quality improves as timing variance drops below threshold
These aren’t baseball anecdotes—they’re empirical facts visible in the natural learning progression of human movement.
Infant Reaching
At four months, infants reach for moving targets with erratic paths, yet they already time the peak velocity of their arm to the object’s motion. The reach may wobble, but the when is already intact.
→ The brain solves for when before refining how.
Child Locomotion
Children crossing simulated traffic gaps fail not from flawed paths but from delayed launch. Adults exit with clean timing; children step too late.
→ Success is governed by initiation timing, not motion geometry.
Infant Catching
Infants switch from spatial heuristics to time-to-contact estimation long before grasp mechanics mature.
→ Temporal prediction precedes refined motor output.
These findings converge on a single truth: timing is always stabilized before mechanical precision emerges.
Implications for Measurement and Study Design
If timing governs feasibility, it must also govern evaluation.
You cannot evaluate mechanical success without first knowing whether the hitter solved the temporal constraint. Outcome-based metrics—no matter how detailed—are conditional. They only become meaningful when the swing occurred within a viable timing window.
This is where most systems fail. They measure swing form, swing path, and bat movement—but they cannot determine if the swing was even possible under the constraint. They diagnose performance in isolation, not in context.
I and the xFactor Hitting System reverses that approach. It begins by solving for timing, then interprets everything else through that lens. It doesn’t treat timing as a background variable—it treats it as the prerequisite to mechanical validity.
Conclusion: Downstream Metrics Are Conditional
Mechanics don’t determine whether a swing will succeed. They determine how well it will succeed—if it was possible in the first place.
Most training systems evaluate outcomes after the fact: path, posture, angles, velocity. But these are all second-order variables. They’re only meaningful if the first-order constraint—timing—was satisfied.
The xFactor Hitting System turns that order right-side up.
It begins where the nervous system begins: with the question of when, not how. It resolves the constraint before it evaluates the result. It tells the hitter not just what happened, but what was possible. And it trains timing not as intuition, but as a mathematically solvable event.
Because once timing is solved, everything downstream becomes trainable.
Until then, it’s all just noise.
