Tom, You are correct - I let my college years buidling coincidence detectors in college for the GRO-COMPTEL as well as television broadcast engineering. in both applications it mattered whether all instruments used were in precisely defined phase relationships and I have been letting this influence my thinking for too many years.
I had just never stopped to think about it before I've just been happily building cables mesured with excruciating precision and building cables for projects using the same spool of cable to ensure consistent delays thinking this was important but in reality is is not.
