I think that such kind of lens measurements, queried out in different laboratories, are not well comparable each other.
Personally I have found that Russian lenses have quality index spread over very broad interval. One can come across with very sharp lens as easy as to a very soft from the same type. Latest Zenitars are maybe a bit better but not very sure.
