Sorry for the misunderstanding, my post wasn't about determining a level where one can rest on one's laurels or where the fun stops. In fact I've advocated in the past for old nodes not to be votable which will stop the phenomenon.
My post was mainly an observation and a math puzzle. As I said, I'm no longer enthralled by gaining XP.
Cheers!
