CV analysis of 43 free throws finds wrist motion doesn't affect makes

jeremyparkphd vibe-coded a custom Apple Watch app to read IMU sensor data, combined with computer vision tracking of shooting motion and makes/misses. After analyzing 43 free throws, he found wrist motion had no effect on makes vs misses — likely because free throws are highly standardized, and grip details aren't captured from this angle. Next steps: more samples and three-pointers. The open-source vision-demos repo (Apache-2.0, 1.1k stars) includes dance-sync scoring, pull-up/push-up rep counting and grading, 3D climbing analysis and more, built on vitpose-plus-large.
