Adding half the gust factor is all very well, but some aircraft float along in ground effect

That is a technique problem not a speed problem hence why I posted that extreme link above to make a point.
We have it drummed into us that landing an aircraft is all about pulling back and back till the aircraft sinks onto the Tarmac, that we should be at a speed near the stall speed but that is far from the truth.
Yes that is a technique used in the majority of especially PPL flying but in strong winds gust and shear the last thing you want to be doing is hanging at 10 feet trying to get the perfect touchdown at or near the stall. In that state you will have little control authority and will be at the mercy of crosswinds or shear
sometimes you need to fly the aircraft on bang it on call it what you want and sometimes at a higher speed away from the stall winds and runway length taken into consideration
