ITU-1770 on which both R-128 and RG2 are based has been tested extensively over a long time and shown to work very well.

The tests on the sample set (which is not small) show quite a good agreement between the two systems. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
