Well, I beg to differ.
In general: Most distributors would not have full mechanical advance present at 2500, so if you adjust by that rpm to 34-36 degrees, you'll get too much advance at higher rpm. With your curve it should be OK. But adjusting with a vacuum line attached should not be done either, partly because any small degree of change in throttle angle will seriously affect the number. Here's a quote from the MSD instructions:
"Total Timing: This is the total of the initial timing plus the centrifugal advance added together. Example: 10° Initial + 25° centrifugal = 35° Total Timing. (When checking Total timing, disconnect and plug the vacuum advance.)"
Another general comment: There's no need to not have a vacuum advance for a street car. OK, it removes complexity, but a correctly tuned vacuum advance provides:
1. better idle
2. better part throttle response
3. better fuel economy
Ben, sorry to give you conflicting messages, but since you are running a vacuum advance, I suggest you do it as I've described
Good luck with it. (If you invite me to Hawaii, I'll be happy to help you...)
