95% of sports bettors lose money long-term. Not because they can't pick winners — but because they manage their money terribly. The unit system is the foundation of professional betting. A unit is a fixed percentage of your total bankroll — typically 1-2%. If your bankroll is ,000, one unit = -20. Never bet more than 3 units on any single event. How we grade our tips: - 1u: 60-65% confidence (value play) - 2u: 65-72% confidence (solid pick) - 3u: 72-80% confidence (strong play) - 4-5u: 80%+ confidence (banker) The Kelly Criterion is mathematically optimal but most professionals use quarter Kelly to reduce variance. The rules: never bet more than 5% of bankroll on one event, never chase losses, keep detailed records, set a monthly stop-loss at 20%.
