I think that this statement is a bit too strong.  Surely, there is some
correlation between the strength ratings on the two lists.  We just have no idea
what it is!

I also would not go so far as to say that comparisons are meaningless -- just
that the numerical value connections are unknown.

An entity that is at the top of either list will be quite strong, and one at the
bottom not so strong -- that much is obvious.
