So it costs about 15 times as much to kill one Aurli devastator than it costs to kill one Argo young. So normally one would expect 15 times as much loot from Aurli.

your observation is correct and your example with radio stations works quite well. However, statistically this means that to estimate parameters for an exp dist with higher mean you'll need more data to get the same accuracy as when the mean is lower. So for Argo I need less data as with Aurli.

The depicted boxplot shows the median in the middle and the interquartile range. Since the standard deviation for an exp dist is the same as the mean, Aurlis will have a larger box.

Your proposal seems reasonable but is unfortunately wrong. Proportionality doesn't mean that.

Please read the newly added "experimental section". There I describe that mean loot might depend linearly on hp. So we have

m Argo = a*300HP + b
m Aurli = a*2800HP + b

For the first mean this leads to a factor of about 4. (a*x1+b)/(a*x2+b) can't be further simplified. Btw, mean for Argo in my dataset is 90 and that for Aurli is 166. The proportion leads to a factor of 1.8. That quite different from 4. The reason for this is, that we have 3 means to consider per mob and that my sample size is to small to cover all aspects. However, I'm at the beginning to analyze this, so I can't conclude more atm.
