Result definition
The headline Estimated live win probability is determined directly by Pre-match win probability and Sets won by selected player; the remaining fields supply the comparison or adjustment required for Live Tennis Win Probability.
Within this calculation, the calculation uses live probability combines pre-match strength with completed sets and current game margin.
In the current scenario, use a separate scenario for a plausible upper or lower assumption.
Treat tennis surface adjustment as a follow-up handled by Tennis Surface Adjustment, without substituting its answer for an input on this page.
Input scope and units
At this stage, confirm that the baseline and adjustment did not both come from the same news.
For this market, keep the new answer beside the baseline.
Conditions to review
At this stage, surface, serve and return form, fitness, opponent, and likely match format should come from the same event.
Practical limitations
Server, point score, injury status, and retirement rules are not included.
In this model, the formula cannot confirm that a matching market remains open for the intended stake.
What to preserve with the calculation
Treat Estimated live win probability as the answer to the narrow question expressed by the visible fields. Save the value entered for Pre-match win probability, then change Sets won by selected player alone in a second case. This comparison reveals whether the conclusion depends on one fragile assumption or survives a reasonable revision.
The label attached to Sets won by selected player matters as much as its number. Verify whether it describes a full event, a partial period, a player opportunity, or a quoted price. Apply the same scope check to Sets won by opponent before interpreting Estimated live win probability or comparing it with another source.
Do not improve the appearance of Estimated live win probability by rounding early. Preserve the available precision for Sets won by opponent and Current-set game differential through the calculation, then round only the displayed answer. If the conclusion changes at ordinary source precision, describe it as borderline rather than decisive.
