A complete bet history is a gold mine, if you know how to dig. Here is a simple, repeatable way to analyze your results so you can keep what works and drop what does not.
Step 1: Separate the categories
Before analyzing, split your bets into groups that behave differently:
- Straight bets (spreads, totals, moneylines, props)
- Parlays and same-game parlays
- Promo bets (bonus bets, boosts, no-sweat)
- Live bets
Mixing a few lucky parlays into your straight bets can hide a losing pattern, or a winning one.
Step 2: Check overall ROI and CLV
| Metric | What it tells you |
|---|---|
| ROI | What you actually earned per dollar (ROI explained) |
| Average CLV | Whether you consistently beat the market's final price (CLV explained) |
| Sample size | How much to trust the first two |
Positive CLV + negative ROI over a few hundred bets usually means bad luck. Negative CLV + positive ROI usually means good luck that will fade.
Step 3: Break down by sport and league
Most bettors have one sport where they are clearly better and one that quietly drains them. Look at ROI and CLV for each, with at least 100 bets per group before drawing conclusions.
Step 4: Break down by market
Spreads, totals, moneylines, player props, alternate lines... Common findings:
- Props show the highest CLV but also the most variance
- Moneyline favorites contribute little either way
- Alternate lines or teasers carry a lot of hidden margin
Step 5: Break down by sportsbook
If one book's bets show much lower CLV, you may be betting there out of habit rather than for price. If one book shows unusually high CLV, it is probably a slow book, and the one most likely to limit you. (Avoiding limits.)
Step 6: Break down by odds range
| Odds range | What to look for |
|---|---|
| −200 or shorter | Are big favorites earning anything? |
| −199 to +100 | Your core |
| +101 to +300 | Usually where props and dogs live |
| +301 and longer | High variance; needs a big sample |
Step 7: Break down by stake size
If your biggest bets underperform your normal bets, your "confidence" is not adding value. Go flat or rule-based. (Flat vs percentage betting.)
Step 8: Look at timing
Bets placed early (hours or days before the game) often show better CLV than bets placed just before kickoff. Live bets often show the worst. Timing analysis tells you when your edge lives.
Step 9: Decide and act
Write down one or two changes: drop a market, raise a minimum edge, stop betting a book out of habit. Re-check next month.

Frequently asked questions
How do I know if I'm a winning sports bettor?
Look at ROI and closing line value over several hundred bets. Positive CLV is the most reliable early sign.
How many bets do I need to analyze my results?
At least a few hundred overall and around 100 per category before breakdowns become meaningful.
What is the most important betting stat?
Closing line value for judging skill, and ROI for judging actual results.
