I think those are good insights. Just a couple of comments:

When the exhaust temps are reduced by advancing timing, turbo response degrades, so time to boost is affected.

Both distributors can give the same maximum timing, but without boost retard there is a negative compromise in what part throttle timing you can run. I think you recognize this well, I just wanted to underline it. Without some sort of manifold pressure feedback, the whole timing curve is compromised. If it is OK at full load, it won't be at part load, and vica versa.
