Analysis of Boss/Lt/Minion breakdown by team size?
not entirely sure what your asking for, are you asking for the ratios per mob for different spawn sizes, like how many boss/minion/lt spawn at x1, x2,x3,ect?
if you could clarify what your asking it might help finding an answer

No, because it's not constant. Different enemy groups have different spawn rules.
Back then it used to be that a 6 man spawn wouldn't have bosses for most enemy groups, but that changed recently-ish
yeah, spawn amounts are not constant, but can be averaged based on the spawn size, a x8 spawn will yield between 0 and 2 bosses (on average, hard settings in AE mishs can have up to 4 bosses on x8 spawns)

Has this been done publicly anywhere?
