On anything but a straight forward gridded system I always tell designers they don't find the remote area they create it.

I think you are right and I am wrong regarding the interpretation of the referenced section. I think there are problems with the referenced section though (i.e. "configuration" instead of "system" perhaps, needs expanded on maybe). I know a Standard can only do so much, and predicting which heads will activate in a given fire scenario is beyond 13, it can only tell us which ones to 'play like' activated, even if that is a long narrow strip. Since head activation is proportional to the radial distance from the center of the plume, I see "remote" areas as round, like they were in the beginning of calcs (so I am told). Square is a close simplification, then as we distinguish big pipe from little pipe we stretch it to include more little pipe, as you alluded to. I am terrified of not calculating the most demanding scenario so I do not rely ONLY on the referenced section-- I have seen the surprising results produced by 'imbalances', elevation differences, etc, to not do some additional analysis sometimes. I am not trying to "tell" you anything, as I believe your reply was only relative to the interpretation of the referenced section.
