It's good that you are taking the losses in a positive way by learning a lesson of how to not chase your losses.
But at the same time the losses shouldn't have gone to 50% at first place. When I say 10% of my savings I make sure to deposit only that much amount for the month.
So that amount is my hard stop and the maximum I can lose. It won't matter if I lose it all in a single day or keep playing with that amount for the entire month.
The next deposit will only be in the next month.
It’s a good strategy, but it seems to me that you are either initially not very involved in gambling, or vice versa, you already have serious experience. I thought so because allocating a budget once a month is a rare event, and if you do not use additional money management (breaking down this budget at least into weeks), then losing at the beginning of the month is very difficult to wait for its end. For example, I am not much involved in gambling and I have discipline but it would be difficult for me to wait even one week if I wanted to play a little.
