However, the Kiwa article doesn't mention detector distortion, which can
be
a significant source of distortion, at least with diode detectors. The
subject of detector distortion has been beaten to death here and on other
forums. One post I seem to recall involved some simple mods to a common
diode detector which significantly reduced distortion but also reduced
output by about 3db.

Or AGC distortion. Fast AGC can be a huge cause of distortion as it varies
the gain of the receiver with the bass energy in the modulation. Slow AGC
can make a huge improvement.
