One thing about gambling is that we shouldn't let it overwhelme our judgment in times of depositing, so I always draw a timetable on my gambling amounts which I will spend on either daily or weekly basis and it also applies on my wining ratios, I make sure even if I saw more good entries to gamble after my wining i always ignore it and take profits from the one I gambled because one thing about gambling is that no matter how many times you lose, something in you will always trigger you to gamble more in other realized the money you have lost and if you don't have control over it you could stand a chance of losing everything you have and that's when it becomes addict.
So like you said is good to control your deposit limits on gambling even if you win or not there should be a certain amount budgeted to gamble and shouldn't increase more than that.
Your approach is commendable and, dare I say, academically sound. For anyone considering a foray into the glittery world of gambling, taking a page out of your book (or should I say timetable?) is a fantastic starting point.
