Project-GC actually has two profile stats pages for each person: one for that person themselves and one for everyone else. The difference is that the personal version includes a few stats related to the home location, which are hidden for other people.
In this case, what happens is probably just an effect of you looking at the pages at different times so that one of you got a page generated before and the other after the system had refreshed the adopted caches. This has nothing to do with being a paying member or not; all members are looking at the same information.
