Proton radius and standard model

Hi Everyone,

in 2010 the CODATA value of the proton radius was: 0,877 fm ± 0,007 fm
Then there were several experimental measures that were around 4% smaller.
Thus in 2018 the CODATA value was changed to 0,8414fm ± 0,0019fm

I think I remember Nassim saying this new value was poking a big hole in the standard model. Does someone know why?

I found the theorical value of the proton radius according to the standard model. I am not sure about the source. Correct me if I am wrong.
0,8745fm so 4% difference with the 2018 CODATA value

and the value Nassim calculated:
0.841236fm so 0,02% difference with the 2018 CODATA value

and this quote from the online course:

some fundamental constants in quantum theory, such as the Rydberg constant, the Avogadro number, and therefore the standard unit value of a kilogram, are derived from the proton radius.
