Have you thought about keeping a record of bets, monthly wins and losses, to track this?.
Is such record-keeping important to you, or do you not consider it crucial for your economy?.
It is not every individual that would consider keeping a record of their betting because it can be cumbersome. It is a fun activity to some people, they do it on their own freewill, and since it is for fun, no need keeping a record or log, especially when they already have it under budget.
I cannot imagine someone who is very busy with other activities in life to judiciously be able to maintain a betting log. It feels like extra work.
