Doing this could help nothing aside from causing disappointment or frustration to the gambler. If we are in a business this is necessary to track where it is going but in gambling, we are just tracking how much we lose which is absolutely some kind of wasting our time and the result is just getting mad. That is a crazy reason for this and I can't imagine someone making this for that seek in the end they only find out that she/he is losing millions while just winning hundreds.
That's one downside of recording everything. You will be frustrated when you see how much the losses are but the positive side is when you see those you can also decide if you want to continue or not. No records means you may forget about your other losses which could also mean that you will keep on gambling thinking you have not yet lost a lot of money.
Well, gamblers have different points of view when it comes to their gambling habit. Some just like to live by the day and do not care if they win or lose while other like this kind of strategy of recording things especially if they want to make a living out of it.
Keeping records has been the best reminder to minimize excessive gambling. It helps the player to recall his losses and puts him on a level of thought that'll change how he wagers money. The disappointing aspect of this strategy is not much. It's actually a nice practice for people to scan through themselves how much have been lost within a range of period. I don't think the losses will come as a surprise when written or recorded on a sheet. The player already have gone through the losses when he did on the casino machine. During recording he'll only reflect on his reaction when such money got lost. This time of self examination will go a long way in helping the gambler think of his gambling habit.
