I also used to play with that kind of approach. 100% of the payment is allocated to wagering. I am lucky that I got it doubled more often. But recently I also think that it is unwise to plan to spend all the earnings on wagering. If I am not lucky then I will be left out with nothing so I agree that we should only allocate a certain percentage of our earnings to gambling so that whatever happens in our session at least we still have funds in our pocket.
Either we are lucky or quite the opposite is not it? In fact, the management is quite effective even though it is simple. But back to the gambler if they have more funds may drop all if you bet and get double what you got. The level of pleasure of people must be different from the target he wants to achieve every time he has a large enough fund. It's just that the distribution management makes me more in control of what I have.
