need help with newer mopar distributor

I was trying to find a number in my dist. that would help me find the total mechanical advance that I would have. The other dist. have a number on the mechanical plate, that you double and that's your total mechanical advance.
I was going to double the number and subtract it from 32, and then set my initial timing.
But I don't see any numbers and it looks like it's adjustable.
I didn't get any paper work with it, so I'm asking you guys for help.
I want to try to get to the strip tomorrow for the first time.
It looks like this.
I guess it's no biggy, I'll could just set it at 4 btdc, but it would be nice to know what I have.
