Frequently Asked Questions
What counts as a good win rate?
It really comes down to the odds you’re getting. At -110 odds you’d need roughly 52.4% just to break even, but at +150 average odds around 40% does the job. Remember, win rate on its own won’t tell you if you’re up — ROI paints a clearer picture.
What does ROI mean for bettors?
Return on Investment (ROI) shows your profit as a percentage of everything you’ve staked. If it’s positive, you’re making money. Most pro bettors land somewhere around 2-10% ROI over the long run.
How many bets before the numbers really mean something?
As a rule of thumb, aim for at least 500-1000 bets before reading too much into the figures. Anything under 100 bets is mostly down to variance and won’t tell you much about your actual skill or edge.
Any tips for getting better results?
Stick to positive expected value (+EV) bets, keep an eye on your closing line value (CLV), pick a sport or market to specialise in, stay disciplined with your bankroll, and keep reviewing your results to spot what’s working and what isn’t.
