Frequently Asked Questions
What win rate counts as good in sports betting?
It comes down to your average odds. At -110, break-even sits near 52.4%. At an average of +150, roughly 40% does the job. Win rate by itself says nothing about profit — use ROI for that.
What does ROI mean in betting?
Return on Investment (ROI) is your profit expressed as a percentage of everything you staked. Positive ROI means you’re in the green. Long-term, pros usually land around 2-10% ROI.
How many bets before the numbers mean anything?
Figure on 500-1000 bets minimum for statistically meaningful output. Anything under 100 bets is dominated by variance and won’t reliably show skill or edge.
How do I get better results?
Stick to positive expected value (+EV) bets, track closing line value (CLV), pick specific sports or markets to specialize in, keep bankroll management tight, and keep reviewing your results to spot strengths and weaknesses.
