spark advance/diablo predator

I have a diablo predator, which has the latest performance tune. Today I was messing around with it and wondering what the actual spark advance was because I have heard that 13 degrees is the best for GT's running 91 octane. When going to the actual setting for the spark advance there was a settting for 0 and then the arrrow looked like it was on the 6th notch to the right from 0 degree (10 degrees stock), does that mean it's at 16 degrees advance? help!
