FAQ

How is this probability calculated?
The estimate comes from models fitted to recorded match data. Calibration and validation depend on the market, league and available sample; the percentage alone does not establish accuracy or a profitable price.
Is this a betting tip?
This is a model estimate, not a guarantee or a demonstrated profitable edge. Where the required result data is available, saved predictions are graded including misses. An unavailable market result stays ungraded.
