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?.
Such log requires the great personal leadership thus not all gamblers could adopt for themselves though superficially it appealing to be a reasonable idea. I personally keep the ledger for my bankroll and even visualize it by plotting the relevant data
the aim being to set the price for my next bet. It is very time consuming but is paying off at the end.
Could you extend your script by adding the ability to plot the relevant data?
