My Euroreef ES6-2 pulls less than 60ml/24hr on a new 75g tank. 70# of LR, 6 fish, 2 shrimp, 6 corals.
10g weekly water changes help keep it low. Bare bottom tank doesn't let detritus settle.
Gonna be hard to conclude anything, because all these factors affect the performance of a skimmer. The same skimmer on my 155g pulled 2 cups per day of black gunk.....
