It says a 43% chance of finding someone better means I should keep looking? This app composes Gaussian distributions but can't even master the basic logic that if there is a less than 50% chance of doing better, I should just lock down the hottie I've got.
Better could mean 10% better or it could mean 1000 times better. If you've got a 10% chance of finding someone 100x better, then the expected return calculation heavily favors dumping your current significant other.
