And you ASSUMING that they are "way off" is also an assumption.
I really don't know where the fuck people are getting this idea of "lol pservers are just guessing! they're totally inaccurate and just complete total guesses!", NO, that's fucking wrong. Pservers base their data on old forum posts from 2004/2005/2006 from people who actually did testing back then. As well as old youtube videos and such. Yeah, there's some inaccuracies here and there, but they are pretty small for the most part.
Not saying we should trust pserver stuff, I'm just sick of people decrying it as "way off guesses" and other bullshit.
