| Notes | Blackbook reported (29 May 2026) that he topped The Great Tip Off's 90-day leaderboard with $3,135 profit from 230 tips. ROI assumes The Great Tip Off's standard $100 even-stake win bets. We could not open the live leaderboard (bot check), so this is a dated snapshot. |

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.
