Standard.
Ive seen people win upto 800k in one year, only to lose it all to huge streaks by not exersizing proper bankroll managment (KEY!). The chance of you going broke if you exersize proper bankroll managment is next to zero (obviously there arent infinately small stakes but you get the idea).
Theres also the idea of GOOD TILT, we all get bad tilt, but good tilt is calling with bad odds when your running hot which obviously means you wont profit in the long run.
I have suffered huge swings, followed by tilt and destroyed my whole roll. I have let stuff goto my head I was +5k the start of this year (considering im a student thats a hella lot of money) then i spent it all, didnt use any of it towards my roll now im building back up, cudda been playing much higher stakes right now.
But seriously, if you can say that your up overall, over a long period of time. You can analyse your game, tell yourself why you played bad and stop blaming the fish, then you are a winning player in the longrun, its not what you can achieve over the short run that counts.
