Hmmm, I feel like a bastard now.

The main point I wanted to make is that the pressure drop alone of a block doesn't mean that much, it's what the block is capable of doing with at that pressure drop.

The nature of centrifugal pump PQ curves is such that even fairly large differences in block pressure resistances (+100%/-50%) result in fairly small differences in the final flow rate (-20%/+20%).
