My base is to have 75 units and flat bet, so I am well within the limit. When I get to 85-90 I either resize the bets or take some money out. Guess I play by the book...
If you play 4-5 games EVERY day (baseball, hockey, NBA) then 2% is kind of high. If you play 3-4 games on Saturday and Sunday (football) then you could get up near 3% or maybe 4%. The more games the lower the percentage must be.
