[@FinalPalladium] More data would be interesting. If my theory about the "boom of 2017" is correct, I would expect to see most of those RPS getting few posts, with the "posts per RP average" going up as time went on, until the boom faded. Knowing how many players joined during the boom and since would also be interesting information to have on hand. though it would be fascinating if all this pointed to something else entirely too. 

I'd certainly be interested in looking at more statistics if you can dig them up.
