So this is a weird thread, i was just contemplating the question of what residential, and commercial: Installers, techs, supply houses etc, are seeing as a ratio of "halves quarters fulls, TQtrs" and then each of those categorys then applied their radius'. say 8 10 12 15 and we can use that ratio to divide the box/boxes in such a way that we are filling up the box at a regular interval and each compartments nozzles be just about (10%) ((just about the same)) lets say. VERSUS: Filling up a small compartment of 10H all the time while the other compartments are full to the brim. Perhaps.... Rod and Ron could fetch us this "grand average ratio of nozzle usage on all projects total" (i dont think there is a way to differentiate residential and commercial) ((i still think we will have some interesting ratios. If we could project long term what we needed to buy. we could by more of it now.
