Then there is one indicator that you can use for measurement - deposit/withdrawal. Because it does not matter if you win 100 times, when you can withdraw less than deposited. But what is the point of tracking such info? And this indicator turns to be useless for people who deposit to have fun. They pay for fun and they dont care if there is anything left on the balance by the end of a day. As for me, when deposit = spend, as well as lose = spend, such tracking makes no use. I dont measure my gambling as profitable or not, I measure it with I had enough fun or not yet.
Because all players are different, maybe someone plays not to have fun, but to test their gambling strategy. In this case, statistics are very important, even if the balance ends up being less than what was originally deposited. But if you play only for entertainment, then it is clear that in this case there is no point in keeping any statistics, or using any kind of application for analytics or statistics. For me personally, winning in gambling is important, even if I understand that this is not done to make money, I want to win, this is an important component of the gameplay that makes me come back again.
In gambling, different people exhibit the habit of tracking their gambling process for different reasons and carefully analyzing the reason of my close friends who engage in the tracking of gambling process, I've found out that their reasons are strong enough to keep doing what they're doing. For some of them, they track their gambling process because they want to always want to go back to it and checkmate themselves if they're making progress in gambling or not while others do it for for record keeping sales. I also know the other few who thinks it's absolutely needless for them to track their gambling process because to them, they only engage in gambling just for the fun of the game and not for anything serious.
Personally, I think it's a good idea for a gambler to always track his gambling engagements and if his track records shows that he's always losing more than winning, the best thing to do os to quit the game of gambling or better still improve his gambling strategies.
