Ben,
I don't know that we've missed that reference to SSU/SSP in 8.6.2.1.2.
I would hope that most of those who'd answered had reviewed the
information that generated the question in the first place, which is in
11.3.1.3, item (2). That clearly suggests that the allowance for the
discharge to be calculated the same as it would for a small room is
acceptable for residential sprinklers as well.

You guys have all missed a major issue with using 8.6.2.1.2 in 2002 or 2007.
The small room rule is for SSU and SSP heads ONLY, not residential heads.
So if you're using LFII residential heads in a 256 sqft room, but you're
spaced 10' off two walls, you have to use the 40 GPM figure, not 25.6.

area of coverage for each sprinkler in the small room shall be the area of
the room divided by the number of sprinklers in each room."
