Even people in Arp's camp describe red-shift as kilometers per second. People who describe redshift as a z= number have an implied relativistic velocity. Given that most mainstream cosmologists don't think of cosmological recession as quite the same thing as spatial velocity, but rather as an artifact of expansion, I think you are playing fast and loose with the language, when you say that I am wrong when I say H is the relationship between red-shift and distance.

Since you live in Chelmsford, albeit a strange one not in essex, i will gladly explain.
The quote is in the biiography "Hubble, Mariner of the universe"
Hubble used to hold these fireside chats every Friday afternoon, when folk came along and used a chalk board to see how things were going.
It was when Zwicky first put forward the idea of tired light that Hubble said.
"redshifts is what we measure and redshifts is what I will call them"
And he did , from then on - because he was a good scientist. Unfortunately, no one knows where he is buried because hs wife scattered the ashes and didn't bother to tell anyone where she scattered them!
Now onto your next point.
Did you ever think it strange that the units of H are "km/s per Mpc?
you see we have two units of distance there.
KM and Mpc.
Why not km/s per km?
Why not Mpc/sec per Mpc?
This is not scientific.
If I were doing this I would have m/s per m,
But hang on Chelmsford, the metres cancel.
The Hubble constant has units of "per sec'. It aint a velocity at all.
It is a conspiracy theory to claim H is a km/sec per Mpc.
H is Around 70 km/sec per Mpc. In real units this is about 2.1x10x^-18 per sec. Which I show to be in
SI units hr/m for the electron in each cubc metre of space.
