All is well and good with whatever method one chooses to use.
The point should be made here,even though many staking plans may not seem perfect,but get into the habit of managing the bets.

I personaly think all systems have a fair 85 % better chance !
But lose on the 25% *not* because of plans and selections, but mismanagement caused either by grief or elation.
You either lose the rent money and lose more thereafter plus what you owe.
Or you lose anyway because a fortune was won and lost it all assuming one is on a roll.

But a plan in action, if followed will limit some of this, would'nt it ?
