Winio forecast accuracy

An open dataset: the share of matches where the model picked the winner correctly. Computed automatically from finished CS2 and Dota 2 matches over the last 6 months and refreshed daily.

Two forecasts are counted for every match: pre-draft, made before heroes and maps are known, and post-draft, made after the draft. A match enters the statistics when a forecast exists for that stage and the winner is known. Forecasts are published on an "as-is" basis, with no guarantee of outcome.

Only rows with at least 10 matches are published: on a smaller sample the share of correct forecasts is not meaningful.
