57% is a great long term percentage, but a 57% capper will still lose 3 out of 7 and go on extended losing streaks. If you're overly sweating short term results, you're either betting too much or you need to rethink your mental approach. If you're betting $300/game, 7 plays a week, your expectation is $210/week, and some weeks will be seriously in the red. It may not be worth the stress.
