That is aademic in this case, since these are supposedly actual cables made
for the job. I think that you really do have to have a large mismatch in
length and capacitance to make it really misbehave though I don't use the
faster speeds here myself.

Higher speed use more than one pair of wires in a cable so they have to
be matched in length - one pair cannot be significantly longer because
the number of twists are different for instance.

I thought each pair was treated separately, and the 2b bytes on each lane
concatenated. Can you provide a link suggesting I am wrong?
