From: | #001 for most skills you can easily get more exp the higher level you are.
The impact isn't as great as you'd assume, since a lot of skills have decent training opts by 80 (and it doesn't take long to get 80, either). Plus level doesn't mean anything for some skills such as in the case of prayer >_>

The halfway mark for range is around 92.5 because yes, 92 is half xp to 99... but as you raise your range level, the higher and more accurate you hit. which means while chinning, even if it's not very much, you are getting more and more xp per hour after each level you raise.
