You can go a lot farther than that, actually. See here for a rundown:

Basically, the car will run better the more you advance it until it hits the peak of its power and then starts to fall off again. He says 12 degrees is a good bet, and that's about where I'm at. Never been happier.

You don't really have to go through the fuel mixture stuff if you don't want, just find a good sweet spot with the timing and leave it. If you have the means to test the mixture and all that you can certainly push it farther.
