Frequently Asked Questions

Variance is the natural fluctuation in betting results due to randomness. Even profitable bettors experience losing streaks. Understanding variance helps separate skill from luck.
Z-Score measures how many standard deviations your results are from expected. A Z-Score above 2 means you're running hot (lucky), below -2 means running cold (unlucky).
Minimum 100 bets for meaningful analysis, 500+ for reliable conclusions. Small sample sizes are heavily influenced by variance and don't reflect true skill.
If variance analysis shows you're running cold (negative Z-Score) but your fundamental strategy is sound, stay the course. Only change strategy if analysis reveals actual leaks in your betting.

Understanding Betting Variance - Am I Running Hot or Cold?

Every bettor experiences variance - the natural ups and downs in betting results. Our variance analyzer uses statistical analysis to determine if your current results are due to skill or luck.

By comparing your actual profit to expected profit based on your odds and win rate, we calculate your Z-Score. This tells you exactly how much of your success (or failure) is attributable to variance.

Understanding variance is crucial for long-term betting success. It helps you stay disciplined during downswings and prevents overconfidence during hot streaks.
