How much retard should I be getting at max boost?

I tried testing my vaccuum advance unit with a timing light and hand pump to check retard under boost. First of all, the unit holds vaccuum and boost, and it will advance with vaccuum and retard with boost, but when I tested at idle I could only get about 3 degrees of retard at 6 psi. Took it up to 10 psi, no change, still only 3 degrees of retard. I am checking this right? Does that sound about right? My distributor should be a better one that matches my red box APC. It should have more retard than this.
Any thoughts or ideas?
