Is it really academic when the sprinklers below the obstructions
triple the number in the area and the heads at the deck might do
little other than activate?

stop thinking about academic realities and embrace the explicit
methodology. After all, do fires activate sprinklers in areas that
are long rectangles, do individual sprinklers discharge water as a
10X13 shape, do you think we are getting the assigned density on the
floor, etc etc? Why get hung up on ignoring the sprinkler below the
obstruction (provided it's not an ESFR and though unstated, it isn't
a mile of 1 inch pipe feeding multiple sprinklers)?

Secondly, NFPA 13 (2002) section 11.2.3.1.8(6) says that sprinklers
below obstructions do not need to be included in the hydraulic
calculations. I am having a hard time accepting this as well
because I'm not sure the potential fire demand will only include
sprinklers at the deck. Actually, sprinklers at the deck may be so
obstructed that very little will effectively get to the fire area.
I would think it be more than likely a combination of sprinklers
above and below. Any thoughts?
