Sounds like a great setup for people who aren't ready yet to move to EFI. I looked at your table and I think you should use a slope rather than a ledge for your vacuum advance. You go from 35 to 45 in one cell which means the timing will jump 10 degrees with a very small change in throttle position. You should use at least three cells to make that transition so something like 35, 38, 42, 45. I'm also not sure that you'll want 10 degrees of vacuum advance. You might want to start out with 5 or 7 and work your way up. 10 is fairly aggressive.
