Zero guesswork.
I'm Harry — a full-time worker who got tired of relying on gut instinct and started doing things differently. I built surface-specific ELO models for tennis and team projection models for NBA from scratch.
The tennis model uses separate ELO ratings for clay, hard, grass and Grand Slams to calculate win probabilities and find value across ATP and WTA. The NBA model projects scores, spreads and totals from team offensive and defensive ratings. Both are tracked publicly — wins and losses, no cherry picking.
Every prediction on this site comes from data. Not hunches, not hot streaks. Just disciplined process and complete transparency.
