I think this method is pure luck and not based on calculations. I've tried this way and always failed in the fourth row, but I'm interested in the 10-15 minute calculations, maybe my failure was on the time.
You don't understand how martingale works and you were started with big base bet with your small bankroll, that's why your balance can only cover for 3 losses. Do a basic math how big bankroll you need to survive or at least in long run with this martingale (you can't afford it even you only started with 1 sat as base bet)
