How the minor-league lines were translated

One row per minor-league stint. Open a row to see each step: the raw rate, the park adjustment, the league/level factor, the age adjustment (hitters) and the resulting MLE rate. Factors are the same ones listed on the MLE Factors page.

Home runs /BIP0.00%÷0.993×0.800—×0.9400.00%

Factors used: level-wide A factors (no league-specific row for this league/era). Park (home-season share, regressed): HR 99, 1B 107, 2B 83, 3B 130, K 98, BB 96 — applied at half strength. Age: age 37 vs a level average of 22.0 → −6.0% on BB/HBP/hit rates (15.0 yr older than average).

Result: wOBA .391 → .326; ISO .062 → .061; BABIP .333 → .282. 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).
