I will say if it makes a profit then that is fine, one thing with place bets is people try to use all ups and such, i agree you get bigger divis but do you miss out on profits each day.

I always say percentage of bank is best, how you work out when you use the percentage of bank is up to you, daily, weekly ,monthly or maybe when the bank has increased by percentage, the only thing i say is don't use it per bet as the swings could turn a winning system in to a losing one.

If you could average 2% profit on the bank each day you could double the bank in just over 1 month.
