This happened to me a few times! They're just trying to give people credit who haven't been given enough due to some flaw that was in the system. What improved my rank again was responding to people's questions and comment on blogs and such!

Hope this helps!!

WOW! But, as I read below from Patsy and Rich, I guess it is still a work in progress.

Hi Paul, there was another update.
It was mentioned that they would still be ongoing.

There was a major ranking update Ambassador Ranking 2017 Update: Pay-it-forward! and there are ongoing tweaks. :)
