Apologies, I made an error in my earlier post, and halved when I shouldn't have. I updated the values now, it's twice what I wrote before.
Also noted that while I have 21b in exploration profit I have over 38b in exobiology, so exo profits don't count as part of exploration profits? Curious that.
Yeah, exobio surface samples only count for exobio rank. Meanwhile, exobio space samples (gathered by research limpets from suitable NSP life) don't count for anything. (Maybe for trade? I never tried that, but it wouldn't matter even if they did.)
It's rather off, but think about it: if exobio profits counted for exploration rank as well, then the valuable samples from a single TWA could catapult a player from zero to well over Elite.
Anyway, I was surprised that several people kept posting their stats here. If you'd like me to, then I could start updating again, though only for the Elite Plus part. Let me know if you would! (Or if people post their stats just to share theirs, that's fine with me too.)
