Reading your ROI
- ROI over a handful of bets is mostly noise. Hundreds of bets are needed before the number means much.
- A negative ROI is the norm, because every price includes a margin.
- Track every bet — winners and losers — or the figure will flatter you.

Over a large sample, most bettors have a negative ROI because of the bookmaker margin. Treat any short-term positive figure with caution.
Is ROI the same as yield?
In betting, yes — both mean profit divided by total stakes.
