Wow! Thanks. This site http://studwww.ugent.be/~kvloeber/BD/Main.html was incredibly helpful.

It is wierd that the highest belt is 41 strength when every other item is 40 though. I also guess aiming for level 20 sharpen and needing like 84+ the normal agility requirement is unrealistic though, but at least now I can figure out how sharpen will affect my agility needs.
