Usually, I hunt 200% target but sometimes go for more depending on mood. Since gambling is all about luck, you can't concretely manage the wins/loss, the single bonus round can pay max win or it can go in red streaks in thousands spins. Having a target is better than randomly chasing streaks on gambling, IMO.
Mood or emotion would be the main factor on this one on which it would really be depending on what you would really be tending to chase for when it comes to profits or winning.
I dont have limits or setting out numbers for this one because i could stop anytime if i do feel that i would need to stop so that my winnings wont really be lost back into the casino.
This is my common mindset whenever i do see myself on greens or in profits.
Play for entertainment and dont stress out yourself on achieving with those goals because just like been said by others that this would really just create out
some desperation if you do really push yourself into limits.
