The 0 head point is not of much use if one is testing pumps for our purposes anyway.

A question though: Would anyone believe me if I were to test a well-regarded pump and its P-Q curve were substantially (a) worse or (b) better than the mfgr P-Q curve? MAYBE a few people, but not many. So I put pump testing down low on the priority list. Exception would be 12V pumps over a wide range of voltage/PWM; THAT would be useful and interesting to many.
