i'm not sure i read it right, but... you included loot, such as bolts and runes, in your profit. that screws everything up, as those are random. you only need to measure two things: profit lost from using runes time profit gained from loot, such as runes and bolts, are inconsistent and do not prove anything about the style used. the only thing the two different styles differ in is the runes used (thus profit lost) and the time it takes to finish a run. the only data you should show are either negative or measured in minutes/seconds edit: exp gained is also possible
