When I plugged in my numbers it gave me information regarding competition for open water feeding potentially causing a problem with fish agression as well as information regarding the chromis doing better in groups of 6 or more, anthias also in groups of 6 or more, etc. As far as herbivore v. carnivore I think this affects the amount of bioload that they produce since "meat" waste fouls more than "herb" waste (which surprises me because I feel that tangs, though herbivores are some of the messiest (biggest pooping) fish I've ever seen). I don't think all of the info relates merely to the calculation of how many fish units you can keep, rather how your tank inhabitants will fare together given their color, eating style, space in the water column, active v. stationary, etc.
