Checking your win and loss history is interesting, but it's not important to me. I've already agreed with myself that whatever the outcome, I'll accept it. So, for me, checking wins and losses is a waste of time. However, if you're curious, it's okay to try it to see the results.
On the other hand, I also believe that there are always some gamblers who win more than they lose. The most important thing for me is to gamble with a small amount of money.
I also don't check my gambling history just like you, but sometimes what usually makes some people go back to the casinos which they have been using to check all their activities is when they are unsure of their gambling spending and they want to recheck their spending record to see if it matches with the budget they planned for in the first place, not just the games' outcomes that have to do with the total loss and total winnings. To me, if you can, it's also important to check if your spending amount is really that small in all time.
If you have time to gamble always it's important you go back to the casinos to check your activities just to be sure if you are making profit or you are losing it will help you check your budget and if you are over spending your can reduce the number of times you gamble in a day or week. From the number of times you have won and lost and the amount involved a responsible gambler should understand his budget and how much he has lost. Your budget alone shows how much you have lost but cross-checking if necessary is not bad also.
