But to totally record it? nah, I don't think that gamblers will go that far. And it will not served any purposed for them and even not going to help them quit gambling for good even if they see how much money the already lost though. On the contrary, it might be bad as you might want to chase and recover what you have lost already. And in turn, you can incurred more loses in your book.
The idea is that if you lose way more than you should then that's not fun anymore, so that means if you are having fun then you are not losing more than you should and that's the point of it. I hope people could see that soon enough and not end up gambling way more than they should. This could result with some situation where things are going to be a little different.
