I can make neither head nor tail of what "H" is supposed to be, in your idea, Peter Wilson - the (local?) constant of proportionality between speed and distance? between the (local?) acceleration and speed? something to do with "expansion"*??

So, what "r > 5 Mpc" observational data leads (or could lead, if one were to do the number crunching) to a determination of the (local) value of H, in the DEILE idea?

*"r(t) = r(0)e^(H*t)", whatever "r" and "t" may be.
