You would use the 16'x16' once you go over the 14' mark

When calc'n EC normally I've always used the design criteria recommendations per the cut sheet (ex. for 14x14 spacing use this psi / gpm etc.) But in this this situation would it be recommend to stick to the 14x14 or 16x16 spacing, or could I use the demand requirements for how the head is space, say 15x15?
