Steven if you want to tone down the PP numbers lower the penalty time scaling slider. Remember the higher the setting for this slider the closer to real time the penalty clock ticks away.
I have mine set in the middle and it seems good. I don't like the penalty time to elapse too quick though. I like to have time to try and set up something before the time is up. And on the other end I like the CPU to have time too. I want to feel the pressure of trying to clear the puck whe I'm shorthanded and if the penalty time slider is too low it only takes maybe 2 clears and the penalty is over.
