This is the comment I was referring too! Yes it is a coyote and not a rabbit, but this started the whole multi system calc. stuff. (By the way I'm agreeing with you, in case that doesn't come thru)

Not only you SHOULD but you HAVE to calc the entire design area. If it comes from more than one system, that is what you have to do. Some time back I was reviewing a design that had several deluge systems, but no walls between them. The designer calcd. one system at a time, and it got installed. I got to review it only after the installation. What would happen if a fire happened at the boundary of two systems. Then both systems would go off. A wet and pre-action won't be as drastic as 2 deluge systems, but still the hydraulically most demanding may be at the boundary.
