It does not beat the closing price. Measured on 1,366 matches with both sides priced, the bookmakers' number predicts results slightly better than ours. A calibrated model is not a profitable one, and we would rather you heard that here than found it out later.
Bar is what we said. Line is what happened.
Players get ratings from the results we track. Clay, grass and hard courts are rated separately, because a player's form can change with the surface. The model uses ATP and Challenger results going back to 2020.
That rating becomes a win chance, and the win chance becomes a price. Bookies build a profit margin into their odds, so we take that out first, otherwise we would be comparing two different things.
The board puts the biggest model-versus-market disagreements first, wherever a model probability and market price are available. We record the result and compare our number with the closing price. A gap is a difference of opinion, not proof of an advantage.

We think Mochizuki wins about 61 times in 100. The bookies are paying as if it is 51. That 10-point gap is where we disagree, and the match settles on the record either way. An example. Today's real board is one tap away.
