Trace the calculation and its limitations

Toronto's run index is (OPS/0.720)^3.8 times4.6; New York uses times4.5. Assumed runs allowed are (bullpen ERA/4)^1.1 times4 for Toronto and times4.1 for New York. Each pair feeds scored^1.83/(scored^1.83 + allowed^1.83). Their resulting values T and N enter (T-T*N)/(T+N-2*T*N), then an authored .035 home adjustment is added and the result clipped to .20-.80. These mappings and coefficients are uncalibrated.

Exactly at ERA3.15/3.60 and OPS.785/.772, a special case replaces the formula with .542. Without that override the same inputs give about .6505. Moving an input away from the exact fixture exits the override: a sudden jump reflects implementation, not measured team-strength change. The .772 fixture is also off the OPS slider's .005 step grid; native slider values need separate verification.

The thirty-point chart accumulates linear changes and sine/cosine terms, then forces final values to +1.42 and+1.15. It does not use the levers, recent records or actual box scores. These run-differential values also do not enter the probability formula.

The series buttons select fixed annotations. A3-0 head-to-head sweep gives a three-game relative standings swing and2-1 gives one, holding other results fixed. Playoff shifts +8.4/+2.8/-2.9/-8.1 are authored constants. The switch does not recalculate single-game probability or a postseason simulation.

Read MLB's Pythagorean winning-percentage glossary, OPS definition and ERA definition for statistical context. These do not validate bullpen ERA as all-team run prevention or the custom OPS conversion.
