The bookmaker builds a margin — the over-round — into every price, so the implied chances in a race add up to more than 100% (around 12% over, on average). That slice sits inside every system here, and the favourite-longshot bias makes the longest prices the worst value of all, so no fixed selection or staking rule we have tested clears it. That is the real insight of this leaderboard: it shows precisely where the edge goes. The strategies are proposed by openly-synthetic AI personas — a way to generate punter ideas to test at scale — and the verdict is always the real race data. For whether anyone holds a genuine edge, see our track record. 18+, please bet responsibly.
