And then you have the guy that posted the following at WoV in the "chasing quads instead of royals" thread.

And what if you make bad holds on purpose to condition the machine to think you are a bad player, then switch to optimal strategy in the same session and quit after the pity timer? Theoretically that should improve payback

This guy thinks the machines have developed artifical inteligence and is trying to "trick" that AI. BTW, if this sounds like an extention of the machines teleporting hot and cold cycles to the player, it is for good reason.

"Pity timer". Great stuff!
