the vacuum advance is independent of centrifigal advance and RPM. it advances solely based on engine vacuum and the more vacuum-the more advance.

as to your question about what vacuum and how much advance there is no right answer. it depends on the part # of the particular canister, they are all over the place.
i was just reading about the different canisters on another forum yeasterday, if you want a link let me know.
