Just the opposite but your reasoning when viewed a little differently will help lock it down. The fire goes up the slope and does not spread out in the normal circle. This results in the adjacent sprinklers (from the channel with the heat) seeing much less of the heat. SO if they are closer to the channel (represented by a spacing of 8 ft) then a normal pressure but if further apart (longer activation time) then a higher pressure .
