Seems the rankings -- for Exobiologist at least -- are bugged beyond the messages given. I just turned in many weeks of specimens, the majority of which were First Logged, and received messages ranking me all the way to Geneticist. But the right-hand panel showed only Ecologist rank. The Commander data panel shows my base rewards ("Profit from Organic Data") just shy of that needed for Geneticist, but I'm far above that rank if the First-Logged credits are added in. So it seems the Pilot's Federation is just as confused as everyone else about which ExoBio earnings should be counted towards ranking. Perhaps the current ongoing update will help resolve this tizzy.
