Factors used: league row EL. Park (home-season share, regressed): HR 107, 1B 94, 2B 101, 3B 92, K 103, BB 96 — applied at half strength. Age: age 21 vs a level average of 24.8 → +5.0% on BB/HBP/hit rates (3.8 yr younger than average). Ground-ball/fly-ball mix moves 1B/2B/3B by ×0.962.
Result: wOBA .358 → .311; ISO .168 → .138; BABIP .331 → .318. 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).
