We provide an overview on the existing determinations on and , as well as on ratio measurements. New world averages for from and for from are reported, combining recent measurements and lattice QCD calculations. We combine these new values with other determinations and ratios of and to ascertain the current knowledge of both fundamental parameters to evaluate the compatibility with determinations from inclusive semileptonic decays. We find: and with a correlation of . These values show a disagreement from the inclusive determinations at the 2.85 level.
