This happened in the Stat Fox Forum MLB tourney last year. Initial success by most, then a drop, were maybe twenty percent of the players were in the positive.
This is where being selective is critical. Because you can select 5 games per day doesn't mean you must. If you're losing take a day off, regroup then start with 1-3.
Anyway, I hope for better results in the future by myself and my fellow cappers.
