Tracking profit and loss reveals your true edge over time. Without records, confirmation bias distorts your perception of performance. Data shows whether your approach is profitable, breaking even, or losing.
Return on investment (ROI) divides total profit by total staked, expressed as a percentage. A +5% ROI over 500+ bets is considered strong. Negative ROI means you are losing money overall.
Break-even win rate depends on your average odds. At 2.00 (evens) you need 50%. At 1.80 you need 55.6%. Use the win rate calculator to find your specific break-even threshold.
Statistical significance typically requires 500–1000 bets at similar odds. Smaller samples contain too much variance to judge edge reliably. Track everything and review at regular intervals.
A void bet is one where the event was cancelled, postponed, or the bet was non-runner/rule-4 affected. Void bets typically return your stake in full and are excluded from win rate and ROI calculations.
