Brian, 1.) It seems fairly common on 13R designs to use heads that need pressures over 7 PSI. If this is true in your case, can you switch to a different head? 2.) Sometimes you can easily make a conversion to a grid system without too much pain and that may help.

Fellow forum people: I have a situation where we have designed and installed a 13R system, it is completely finished and wham-o we fail the bucket test! Our system was designed based on the flow test provided by the city fire dept., turns out that a test taken now with the failed test shows a 25% drop in static & residual pressures, hence the failed test. Of course the owner is looking to us to pull a magic rabbit out of our #$% , err I mean hat, we have tried a few different things but with that big of a pressure loss there's really not much we can do. I don't feel it's our liability at this point since we went off the city's water flow test and per the calc's we were good, any thoughts?
