anti surge control

Instead of using Pd/Ps corrected for compessor suction pressure on the top half of the anti surge eqauition and DP in the bottom half, don't we simply use Pd-Ps on the top half and DP on the bottom half. Doesn't this mean we don't have to use a pressure correction on the top half of the equation for variation in the flow element due to changes in compressor suction pressure?
