Exactly - I should have used the term "looking over" instead of "reviewing" in the initial message. Yes the drawing shows 20 sprinklers enclosed in a nice shaded box. However the calculation entry data shows each sprinkler at 95 sq ft. So based on a first glance at the shaded area and the graph things looked OK but they weren't.
Now I'm "reviewing". Bill Brooks William N. Brooks, P.E.

It doesn't help that the Sprinkler Handbook babbles for several pages on counting sprinklers (at least it did the last time I checked that section). What a waste of space in a good book!
