I flat bet every game.
Sure, I LOVE some games and merely like others, but the difference in the end, for me, is minute. And it would be very easy to talk myself into a LOVE game...
I love the idea that by betting flat I GUARANTEE a winning season if I hit 53% winners. By unit betting it would come down to how the large bets do...the others are just for action.
In the end, unit bettors are about the same as flat bettors. 1-5 unit bettors are going to have a winning season if their 4 and 5 unit games win...it really doesn't matter what their 1 and 2 unit games do, unless they hit an unreal high percentage of those. And in that case, they would have won a lot more money betting flat.
Now, a unit system that makes sense is a 5, 6, and 7 unit system. Even LOVE games don't cover better than 70% over any significant time period. Like games should cover above 50% or you shouldn't be playing it. So why would you bet 3 to 5 times more money on it than a game you like?
Having a unit system which more accurately depicts the real probability makes more sense to me. I just bet flat to make it easier and guaranteed. Either I pick winners, or I don't.
Even Ace-Ace admits he loves action and advises players that bet his picks only, to stick to his $2000 games.
