lol this thread has become a thread about skill...
If skill follows a normal distribution (like all other human abilities/features) then it should be something like that:
But that doesn't explain how come that on etpro publics almost everyone is low+/- with a few meds and the occasional high, no poke and no afk-skill, I guess they give up or they go to jaymod, so only the upper part of the curve is there.
That makes sense also because if you start playing video games in the first place (and you keep playing) then you need to have a bit of reflexes to begin with, so the lower part of the population is not there at all.
