Break-even win rate at 8/11

The implied probability of 8/11 is about 57.89% (1 ÷ the exact decimal odds, shown rounded). That is the break-even win rate: if you bet this price many times on win-or-lose bets, you need to win more often than that to come out ahead. Whether a 8/11 bet is good value depends only on whether your honest estimate of the chance beats that number — the EV calculator does the comparison.
