Read the explanation

Actual formula starts fifty, adds thirteen times point seven for first-serve difference, fifteen times point four five for break-point difference, and six times point eight for ace difference. Total seventy point six five displays seventy point seven percent. Bars compare base and calculated probability at seven pixels per point. Match records and probability validity are unverified fixtures. Holding other inputs fixed, ten percentage points higher first serve adds seven probability points, giving seventy-seven point six five before display rounding. Bars share zero at seven pixels per probability point. Executable coefficients differ from source comments; narration follows actual arithmetic. Five additional entered aces times point eight adds four probability points, giving seventy-four point six five. Bars share zero at seven pixels per probability point. Source clamps outputs between twenty and ninety-nine point four. Native milestone JSON, actual baseline reset and resize preserved; exported historical milestone is not the live probability model.
