Well possibly adding a Monster exp variable there say the last mob on your
list is some 10K mob, you need to kill enough mobs to reach that exp, say 100
* 100 exp mobs / 10 1K exp mobs etc. killing a bigger one could drop multiple
entries...
as for the list, maybe make the list as big as some % from your totals, dunno
might be quite messy. and might fuck up those with the highest totals but
well...
