Set it where you get the highest vacuum reading at idle. As the timing and vacuum changes, so does idle speed. So you just have to keep adjusting both at the same time until you get it right.
If you don't have a vacuum gauge, you can use a bowl of water. Set it on the cowl, and adjust the base timing and idle until the ripples in the water are the smoothest.
Dyno time with a good tuner will get the most accurate results with the least amount of effort. But if you know what you're doing, you can get good results with street and strip tuning.
