Every project here makes its predictions in public, stores them before the event, and grades them after — nothing is edited after the fact. The point is to show whether a method works, honestly, over time.
Each project has its own pages: what it predicts this week, its running record, and a "How this works" page that explains the method, the data sources and when the numbers update. Records are shown next to a public benchmark wherever one exists (for sports, the closing betting line) so you can judge a model against something real rather than against itself. Nothing on this site is betting, financial or legal advice.
