Zone Size Factor: Strike zone width relative to league average (1.000). Higher = wider zone, favoring pitchers.
K Factor: Strikeout rate in this umpire's games vs league average. Higher = more Ks.
BB Factor: Walk rate adjustment. Higher = fewer walks (wider zone suppresses walks).
NRFI Rate: % of games with no runs in the first inning. League average is roughly 55%.
