FREE RELEASE: Pitch Profiler's Arm Angle Estimator
Our ML model predicts arm angle with 98.6% R², cutting error nearly in half vs geometric methods (47.5% MAE reduction).
Outperforms traditional calculations on every metric.

The Scatter view combines the Magnus distribution ellipse with individual pitch points showing actual movement.
A pitch-by-pitch look at how far each throw moves off the expected spin path due to seam and gyro effects.

The Distribution view overlays two ellipses.
The filled ellipse represents the distribution of Magnus movement. The outlined ellipse shows the real movement. The space between them highlights how much non-Magnus force alters each pitch.

The Movement Components view shows the full breakdown: Magnus only, Non-Magnus only, Total movement, and a vector connecting spin-driven movement to the real path.
A simple way to see which pitches rely on spin and which get extra help from the seams.

The Movement Components page is now live on Pitch Profiler!
A major step forward in breaking down pitch movement into Magnus and non-Magnus sources, giving a clearer view of how spin, seams, and gyro actually shape every pitch.

Pitch Profiler’s offseason modeling update is a double whammy.
2025 data gets rolled into every model, and proStuff+ plus proPitching+ will now factor in non-magnus movement.
Patreons also get an ALL NEW Movement Components visual.
Coming soon!
