That would show whether it was needed or not.
It wouldn't show = to code requiring flow of two more heads, which would 
provide better protection even if they weren't needed.

Not saying it won't work, saying it isn't equal to #13.

Perhaps the "=" is in the extensive testing done by FM demonstrating the need, 
or lack thereof, of adding the sprinklers to the calcs?

Cause it sure is tough to come up with written technical substantiation to 
support Equivalency when all you do is less.
Same thing Bill Brooks pointed out on larger SF/system, although I'd rather 
write something on that, maybe lessening # of valves = less chance one is shut.
When all you do is omit flow cause the other guy says you can, where's the = or 
better?

Subject: ESFR Calc 2 hds under obstructions

NFPA #13 (2010) 16.2.3.5. Does the ROP/ROC for 2013 NFPA #13 contain any 
proposals to drop the requirement to calc an additional 2 heads under 
obstructions below ESFR systems as FMG has done?
