What is a CULTURAL VALUE?????????
On a post that you removed Cap- you say add 25 knots as the "cultural difference" between Vref full flap and Vref flap 1+F, when I already explained that there is only a 10 KNOT INCREMENT from the QRH.
Oh by the way, landing on 03R in JNB the other day in a 343, (short runway) and not using the brakes and only full reverse down to 70 knots - we were doing about 30 knots as we approached the end of the runway, at near max landing weight. With alternate brakes and FULL reverse to a standstill it would have been a cinch, especially with blown tyres. (loads of drag, basic physics old chap)
I still do not see the what you are trying to say
