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?.
I once did that, and I feel frustrated from them on I stopped doing that. Unless you are comfortable with the amount you allocated and the result that you will see, which many gamblers are not.
I don't see the benefit of tracking your bets because the fact is you cannot beat the house, and gambling is not something you are going to make a profit, so why track it?
