Recently Published Values Of The Hubble Constant
Below is a table showing some of the recently published values of the Hubble Constant, H. The list is not intended to be complete. The sample was chosen by doing a search in the ADS database. If anyone is upset at being left out then please send me an e mail and I will include your result.
To save space we will give the constant 'hr/m per cubic metre of space' the symbol 'A' (A for Ashmore's constant -look, it's my web page and it was me who thought of the paradox so I will do as I please!)
A = hr/m
                  per cubic metre of space
Where, A is the ashmore constant; h is the planck constant; r the classical radius of the electron and m is the rest mass of the electron

Average value   1.0A
You will see that all the results from all methods are close to hr/m per cubic metre of space. What is interesting is that the average of these results is 1.0hr/m (and remember, these are amongst the most recent and therefore one would assume the most accurate measurements of H)
i.e. H = hr/m per cubic metre
As I said before, some coincidence eh?
To get an unbiased sample, the title words "Hubble AND constant AND measurement" were fed into the ADS database search engine and 'return 100 items' chosen. Of these, all the papers giving an actual value for H are listed above. In theory, all the most recently measured values of H over the last 5 years should be listed.
So there you have it, whichever technique you use to measure redshift and the distance to nearby gakaxies in order to find the the Hubble constant, (gravitational lensing, Cepheid variables, X ray emission, supernova), and whether you measure it from Earth or the Hubble space telescope, all the values come close to a combination of the parameters of the electron and the planck constant. With the expanding Universe and the Big Bang theory, will cosmologists still stick to their theories and reject tired light? Probably!
