I am quite comfortable that my comments are compatible with both circulars.
Consider that
(a) the Boeing 20kt max additive is for the approach and is not intended to be carried into the flare
(b) the factored W/V built into the AFM numbers provides a significant margin
(c) entry into the flare significantly outside "normal" parameters is adequate justification for a missed approach unless the excess runway is significant.
(d) there is implicit an understanding that the pilot will consider all factors in determining just how critically he/she views the maintenance of profile etc. and, in particular, touchdown zone and retardation effort.
We can, of course, continue to agree to differ.
