Calculating a monster's 'score'

Or just calculate how much % you get in X place for 1min, then:

%/min x 60 = %/hour.

It would be impossible to calculate it without visiting the map, cause you need at least these factors: time spent between spawn points (ladders etc), monster hp, monster exp, your dmg, your accuracy, mob skills(stuns and stuff), skill delay, skill range etc etc...
