Prematch conversion check
Estimate how often you would clear a perfect-conversion fixture if every chance is an independent attempt. Enter the Goal chances printed on your prematch card and the conversion rate you actually expect.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
Use the Goal chances number from the current prematch card. Chance is your own expected conversion, not a published shot formula. If the card says ALL chances must be converted, enter 100 and read the result as the chance of a perfect card. A softer To win target is not modeled here.
