No. I don't.
I believe it does not make much sense to track ones losses or winning when comes to gambling. Because, as we all know, casinos will always win over the gamblers in the long term, so as soon as loses start to accumulate then that tracking will encourage us to go after those losses to improve our statistics.
On the other hand, I believe there is nothing wrong to keep track of our complete wager of accumulated wager, for the purpose of comparing our tier in the VIP program of the casino with the bonuses and rewards we get on there. For example, if he gambled for a whole month three times a week and then by the end of the same month we received a bonus of 20$, some could argue that is okey or according to our range within the casino, however it takes a look at the completely wager of that month to know whether it is a fair amount of not. It is not the same receiving a 20$ bonus on a casino when one wagered 500$ than receiving the same bonus after wagering 2000$.

Another situation where one would like to keep track of wins and losses could be whether one needs to calculate taxes on that money lost/won. In the case of the United States and other republics, if one has lost enough to the casino, one could apply to a tax deduction.
