StrengthPowerSnapshot

readonly struct

Strength and conditioning measurables from S&C sessions. Rotational power is the primary
predictor of bat speed and throw velocity. Grip strength correlates with spin rate and
bat control. Explosiveness (jump metrics) predicts sprint acceleration and first-step quickness.
<para>DEPENDENCIES: None. Direct measurement from radar gun (med ball), force plate (jumps),
dynamometer (grip), and scale (body weight).</para>

ThrowingArmKinematics

readonly struct

Throwing arm kinematics and joint loading. Critical for UCL/shoulder health monitoring.
One per throw rep. Captured from CV skeleton tracking or wearable IMU.
In training: used alongside PitchTrackingSnapshot for bullpen reps, or standalone for
long toss and positional throwing drills.

TrainingProgressDelta

readonly struct

Longitudinal progress tracking for a single metric across training sessions.
Compares a baseline measurement against the current measurement to quantify improvement.
ProgramPhase maps to the training cycle (e.g., 1-8 for an 8-week program).
<para>DEPENDENCIES: Requires two ConsistencyProfile snapshots for the same metric —
one at baseline (program start or prior assessment) and one at current evaluation.
Delta and PctChange are computed from ConsistencyProfile.Mean at each timepoint.
TrendSlope is the linear regression slope across all session means in the window.</para>
<para>FEEDS FROM:</para>
<para>- ConsistencyProfile.Mean (at T0) → BaselineValue</para>
<para>- ConsistencyProfile.Mean (at T1) → CurrentValue</para>
<para>- CurrentValue - BaselineValue → Delta</para>
