The only reason for recording gambling activities imo is to track how much is lost and to realize when to stop, when it is enough for this week or month. All other stats are so random and unconstant, that it is impossible to build any analisys on that. I hope everyone understand, that there is no win strategy from result analysis in gambling.
Yes, it can be very useful and able to have positive impact on gamblers who really have wise and responsible attitude towards all the results of gambling activities that have been carried out and of course they can take into account what should be done in the future to improve.
But for those who have quite high emotional temperament and gamblers who measure everything in terms of profits and are unable to accept any bad results, I would say that it is not recommended.
I think that those who are more easily emotional in certain conditions and are unable to accept every bad result or the amount of loss that is certain when calculating the amount of loss can make them feel like they don't accept it and in the end they feel emotional about betting again to recover the loss.
This kind of thing is quite worrying and whatever it is, if gamblers cannot behave well it will only have worse impact.
After all, this is just game and gamble, if always do it with excessive ambition it can also give you deep disappointment because gambling always makes the gamblers themselves have very small chance of winning.
It better to forget about wins and losses, think about coming to deposit money just to have fun and this can be much more meaningful.
