Compares each player's edited/projected performance (from the roster export, run through the real ranking engine) against what they actually did on the field, across career / last-3-years / last-year / current. Re-run this every season as new performance exports come in — it's the empirical check on whether the ranker's assumptions hold up, and it surfaces who's trending up or down for trade purposes. Does not modify the ranking engine itself — this is a read-only analysis layer on top of it.

Hitters performance — export each tab of your stats spreadsheet (Career / Last 3 / Last Year / Current) as its own CSV and drop each in the matching box. Career is required; the others are optional but the more you provide, the more reliable the report.

Hitter hand reliability
actual OPS minus the roster export's edited/projected OPS (25% vL + 75% vR blend), grouped by bat hand. A more negative number means the edits overrate that group relative to what they actually produce. Minimum sample size per period shown in parentheses.
Pitcher hand reliability
actual (OBP+SLG allowed) minus the engine's projected W_OPS, grouped by throwing hand. Same idea as above, for pitchers.
Trending down (regression / possible sell candidates)
Most recent season (Current if provided, else Last Year) well below Career baseline, min. sample size in both windows. "Prior Yr OPS" shows the season before the recent one when available, so a dip that's already recovering shows up instead of getting flagged as a flat decline.
Trending up (possible buy-low / breakout)
Most recent season (Current if provided, else Last Year) well above Career baseline, min. sample size in both windows.
