@903124S If by non-magnus you want to measure ssw, you won’t capture it like this bc ssw induced movement can actually be exactly in the direction of magnus
@pirates_at448@Trevor40878381@LanceBroz@pitchprofiler No, the smart teams either: a) can give almost every pitcher a good/better pitch b) are so good in their analysis they can identify before acquisition what they can change
@903124S I see. No it shouldn’t be regressed to the mean. Like FIP, WOBA, xWOBA, etc. it is, at the end of the day, a descriptive metric that happens to be predictive. If you are using it to project pitch type RV then sure do some regression to mean. Otherwise, no.
@903124S 1. Doesn’t matter
2. No
3. No
Model should see a pitch as appearing out of a pitching machine or another universe/dimension (besides biomechanical effects, most obviously release characteristics, most commonly used: arm angle, though this is not close to the full picture)
