The reasonable and obvious action is to follow the same maximum area
as driven by the density BUT the amusing part is that there was no
actual guidance. This is a legacy from the old days when high piled
had intended meaning. This was fixed at the recent ROP meeting.

The function of maximum sprinkler spacing is either:
(1)a function of the required design density, as addressed by
NFPA-13 and all the previously referenced tables...
(2) or a function of the listing of the sprinkler you wish to
utilize, (ie extended coverage, ESFR, etc)
It also appears to me that it doesn't matter whether it is high-
piled storage or miscellaneous storage, by definition.
The requirements are still predicated on the required design density
(ie <0.25 gpm or >/= 0.25 gpm) OR the sprinkler's listing.
The only other caveat that comes into play are any other specific
requirements or allowances for spacing in high-piled storage
arrangements, such as in-rack sprinklers, etc.
