Factors used: level-wide A+ factors (no league-specific row for this league/era). Park (home-season share, regressed): HR 147, 1B 104, 2B 110, 3B 80, K 101, BB 108 — applied at half strength. Age: age 22 vs a level average of 22.8 → +1.2% on BB/HBP/hit rates (0.8 yr younger than average). Ground-ball/fly-ball mix moves 1B/2B/3B by ×0.989.
Result: wOBA .455 → .352; ISO .242 → .170; BABIP .425 → .362. Both wOBAs use the same linear weights, so the change is the translation alone. The MLE line is not regressed to the mean — regression happens later, when seasons are blended into a projection (how).
