In the airline industry it is rare to see pilots fine tuning their airspeed to arrive at the flare right on VREF (conditions being appropriate of course). It is a good bet that mostly their speeds are padded on purpose; or just plain "sloppy" because of long runways and near enough is good enough. Applies to general aviation types as well; hence in this Forum
V Ref is a 50' threshold crossing speed not the speed you'd be starting the flare. In my experience near enough is most certainly not good enough when it come to airline flying.
