How the Rating Intelligence Engine works

Every card carries OOTP's full rating set on a ~1–250 scale. The engine normalizes each rating to 0–100, weights it by how much it actually drives run scoring, then re-weights everything for the run environment (RE) you're playing in. The same card is worth different amounts in a pitcher's duel versus a slugfest — that's the core insight tools like cwhitstats and beanecounter under-exploit, and where this engine aims to win.

Run environments

Low RE

~3.5 R/G

Pitcher-friendly. Contact, on-base skills, speed and defense win games. Power is muted.

Medium RE

~4.5 R/G

Balanced, modern-MLB-like environment. On-base and slugging both matter.

High RE

~6 R/G

Hitter-friendly. Power and HR-suppression dominate; defense and speed fade.

Extreme RE

~8 R/G

Slugfest / coors-on-steroids. Home runs decide everything; play your biggest bats and HR-limiting arms.

What each rating does

Hitting

Contact RE-neutral	How often the batter makes solid contact and avoids weak outs. Drives: Batting average / hits
Gap Power RE-neutral	Ability to drive balls into the gaps for extra bases short of HRs. Drives: Doubles & triples (ISO ex-HR)
Power ↑ in high RE	Raw home-run power. The single biggest swing factor in high-RE play. Drives: Home runs / SLG
Eye RE-neutral	Plate discipline — drawing walks and working counts. Drives: Walks / OBP
Avoid K ↑ in low RE	Ability to avoid strikeouts and put the ball in play. Drives: Strikeout rate (fewer Ks)
BABIP RE-neutral	Quality/luck of balls in play turning into hits. Drives: Batting average on balls in play

Pitching

Stuff RE-neutral	Swing-and-miss quality. Higher Stuff = more strikeouts. Drives: Strikeouts (K/9)
Movement ↑ in high RE	How much pitches move — suppresses hard contact and home runs. Drives: HR & hard-hit suppression
Control RE-neutral	Command — limiting walks and staying in the zone. Drives: Walks (BB/9)
HR Allowed (pHR) ↑ in high RE	Tendency to surrender home runs (higher rating = fewer HR). Drives: Home runs allowed
Hits on Balls In Play (pBABIP) RE-neutral	Ability to limit hits on balls in play. Drives: BABIP against
Stamina RE-neutral	How deep a pitcher can go — separates starters from relievers. Drives: Innings per appearance

Baserunning

Speed ↑ in low RE	Raw foot speed — infield hits, extra bases, range overlap. Drives: Baserunning & infield hits
Stealing ↑ in low RE	Stolen-base technique and success rate. Drives: Stolen bases
Baserunning ↑ in low RE	Instincts taking extra bases and avoiding outs on the bases. Drives: Baserunning runs

Fielding

IF Range ↑ in low RE	Infield range — getting to more balls. Drives: Infield defense
OF Range ↑ in low RE	Outfield range — covering more ground. Drives: Outfield defense

Scoring formula

Normalize each rating: value / 250 × 100.
Multiply base weights by an RE factor (Power & HR-suppression scale up as runs/game rise; Avoid-K, Speed & Defense scale up as they fall), then renormalize so weights sum to 1.
Hitters: offense × off-share + baserunning × br-share + defense × def-share, where defense and baserunning shares grow in low RE, and defense is multiplied by position scarcity (C/SS/CF premium).
Pitchers: weighted run-prevention score blended with stamina (starters weighted for stamina, relievers largely not).
Value efficiency = score / price × 1000 — the best points-per-PP buys.

Weights are fully exposed in the Card Explorer so you can calibrate against real PT results. Defaults reflect modern run-value research (on-base skills weighted slightly above raw average; power the single biggest hitting lever).
