One who's got this allocation could just max out the 10% for entire gambling. But it's true that not everyone will be consistent on it because this serves as a guide and we as the ones who will follow it will still have the decision to make with the temptations that we see.
More temptation to go beyond the allocation limit that has been made in the event of a defeat will make them more emotional to play more and return the defeat.
Some succeed, but more fail to turn the tide even more and more losses are incurred.
This was due to their own greed and carelessness, unable to control it to stay within the prescribed limits.
That's where the control comes in that we always say that each gambler should have. So, if a gambler is a good spender and budget maker but when he losses his own control, that's where the temptation gets in and will use more funds that he's allocated for gambling/recreation. Emotional control is still important and it's not easy to make a plan, a budget and even execute them. Someone who's got the willpower to do it really wants to change their way of gambling and wants to follow their own rule that they have strictly set and implemented for themselves.
