A fogger system as you are talking about is utilized differently with a pro mod. Most of the pro mods are shooting more than 500 shot, and if utilizing a nozzle, it is in the intake directly pointing at the valve - not like most street cars.

It doesn't matter what motor you are spraying - a 100 shot is 100 hp. If you get 78 hp, then you are shooting an 78 shot. Different bottle and fuel pressures can affect it, as well as humidity. Its easy to just give a rounded number, which is what most people do.

And yes, I have spent a lot of time testing nitrous on the dyno with many cars. Everything from single .018 jets on up to multi-stage.
