A 55% record can lose money at steep prices and a 45% record can make money on plus odds. What matters is whether you win more often than the price needs.
Units and ROI
Units are profit measured in your usual stake (1 unit per bet). ROI is units won divided by units risked. A steady +3% to +5% ROI over hundreds of bets is excellent.
Break-even win rate
At −110 you need 52.4% to break even. LineScout grades every pick in public so you can check its record the same way.
