The touchdown speed is irrelevant.
Try that at on my 400 yard farm strip, the touchdown speed is very relevent.
Most of us are talking about the "smaller range of aircraft"
I also fly multi engine high perf a/c and I do follow the POH.
There is NO reason for a PPL in a PA28 to come over the fence at 75 knots or above when the POH at max weight is about 63 knots and in most cases 60 or less is OK
