Great post slotsmonster and all excellent points.
One of the issues I have is after hitting a good win I generally increase my betsize which is fine because it gives you a chance to hit big but if I get on a losing streak I find it really difficult to put my bet size back down.
So I would say if you hit a decent win then increasing your bet size is ok but make sure you limit your self to a set amount of spins at this level.
I get just as much pleasure out of battling away with my last few $ and then hitting a win that will keep me afloat as hitting a win for a few hundred so cashing out along the way and leaving say 200Xbet to play with would make more sense, all notes to self
