I could be wrong, but I don't think the cam synch has anything to do with how the box controls ignition. I don't run a cam synch, at the moment, only a crank sensor. Whoops... rotating the distributor would only affect the cam synch... the crank sensor would have to be adjusted too, but you get my point, I think. My question still remains. The point I'm considering is whether it all works out to the same tune, even if the numbers on the screen are off.
