It's pretty accurate. I've never thrown a controller, though. Instead, I talk to the console:
"Are you happy, Nintendo!?! Is this what you want? You enjoy watching my PAIN!! Well guess what! I WANTED to lose!!! You fool. YOU GAVE ME EXACTLY WHAT I WANTED!!"
And then, when I beat the stage/boss/puzzle, I tell the console that I was lying and that it fell for my trick.
-This might explain why my Xbox 360 died that time...........
