Do high stakes cash players make more than sng ones?

I saw some graphs on 2+2 where sng players are usually showing off there 25-100k graphs, but cash players usually have 200k + graphs.

Sng players do usually show their graphs that can be found online. I guess poker table ratings isn't that reliable for cash players?

I'm talking about coaches graphs not just random players

I don't think that poker table ratings is 100% reliable since a lot of results don't appear, at least when I searched for some friends results, they don't match.
