Racket Form
Biomechanics you can scrub, multi-source gear intelligence with skill spans and quirks, and a court that remembers every one-lever change.
Method
Specs advise; logged feel decides. Play scores and court-ready verdicts come from mass, SW, RA, pattern, string, and tension — not the model name. Launch, path, and quirks are Racket Form coaching models, not laboratory certificates.
