The scoreboard
How good is each source?
Every tip these sources publish is graded against the real result. This is the whole record — not a selection of it, and not anything they claim about themselves.
| Source | Sport | Market | Pick type | Graded | Hits | Hit rate | Avg odds | ROI | Brier |

Why some ROI figures are withheld. ROI is computed only over tips that had a quoted price to settle against, at the best price seen. Where fewer than 20 such tips exist we show the count instead of a percentage. A −100% built from two bets looks exactly like a −100% built from two hundred, and only one of them means anything.
Avg odds is why two identical hit rates are different businesses. A source hitting 62% at an average price of 1.70 makes money; the same 62% at 1.45 loses it. And a double chance covers two of three outcomes, so it wins about two thirds of the time before any skill is involved — never read that rate next to an outright one.
Brier score applies to sources that publish a full probability distribution rather than a single pick. It measures how well-calibrated those probabilities were — lower is better, 0 is perfect. A hit rate throws away everything a distribution says except its most likely outcome; this does not.
