and got a formula for the XP needed to lvl up for each lvl
don't know if it all correct and don't know if the program missis some XP or so

Crafting:
XP needed=(2,5*lvl^2)+200 or
XP needed=(2*lvl^2,04)+200
both have nearly the same values but they seem to be a really close asumption, the 200 are just guessed

harvest could be like this:
XP needed=(47*lvl^1,5)+200
but thats mostly guessed cause I only have XP data on lvl 200-240 so could be totally off for the lower lvls
