It's obvious that your site took a much harder hit than most (but not all), so the question is, "Why?" We've discussed this here before, but AFAIK, have never come to an adequate conclusion about the cause(s).
If you've tested the headers with a good tool that's guaranteed to show all the "steps" (some do not) and you're getting a single 301-Moved Permanently redirect to the correct new URL in every case, then we can cross that off the 'suspect' list -- It's easy enough to find, because it's one of the very first in the list.
What reasons can you think of that G might not have "trusted" your site as much as you like?
