Ok, if you read that it is not an efficiency, it is how much it will remove in 24 hours.. an eficiency would be how much it would remove in one volume change of the skimmer, which is what this discussion is about having a flow rate matched to your skimmer. so if my skimmer had a flow rate of 600gph, I would call the efficiency the amount of crap removed from 10gal of water in 1 min, a power efficiency would be how much is removed compared to the power input.

so ya the 80 and 20%s have nothing to do with what we are talking about really.
