I was thinking more having an RMS max target dBA/dB(SPL) and a cut-off above that to limit instantaneous volume rather than requiring a particular level for the night.
I'm in the UK; I know a little about phase effects having set up a few room level PAs (5 instruments, 3 mics, 6 speakers, single board; that sort of size). However, I'm not familiar with large set-ups as I've only attended smaller concerts of the order of 100s-1000s of people.
