Understanding ROI

ROI = (Net Profit / Total Wagered) × 100

Most professional sports bettors aim for a 3-7% ROI over time. Breaking even (0% ROI) is actually beating most recreational bettors who lose to the vig.

⚠️ Sample Size Matters

You need at least 500-1000 bets to get a statistically meaningful ROI. Short-term results (under 100 bets) are heavily influenced by variance.
