i might do this later
i currently have 10 mil, according to scape-xp.com, alching yew comp bows is only a -27 loss
it takes 200,530 high alches to go from 55-99
so according to this, 200,530x 34= 5,414,310 loss of profit
yew comp bow + nat rune cost in total 2007 gp for 1 high alch
so with 10 mil i could buy 4982 alches. mhm
and get back 8 mil, repeat, get back 7 mil, repeat until im halfway to 99 mage
