Glancing through it, it almost appears that it's almost copy and paste. It has so many tangents and subject splices, it is hard to follow. It appears to be arguing that the Planck constant is defined partially by mass, which has never had an high-precision value SI unit. The Avogadro project has determined a high-precision definition the Avogadro constant. The Rydberg constant is known to high precision; therefore, the two can be used to together to find a high-precision value of the Planck constant. Also, once a fixed definition of mass through physical constants is made, we will have an exact definition of Plank constant.
