| Notes | Recomputed by us at level stakes from every win bet in Winning Edge Investments' downloadable results spreadsheet (11,780 bets, 2,436 winners). The service itself advises variable unit stakes; its own staked figures are on the results page. Place, exotic and multi bets are excluded. Raw data kept on file. 3 early winning rows have no recorded odds and count as losers. |

The range is our own calculation from the published record, not the tipster's figure. Winners are paid at different prices, so the true range is at least this wide. How we calculate it.
