Can definitely not agree with generally retarding the throttles at 20-30 feet.
Sure, it gives you consistent "ok"-landings, but from my experience (around 1500 landings) the best landings resulted from keeping some power (maybe 45-50% for F40 on a 733) until 10-15 feet with a late break at around ten feet.
Consistently produced very gentle touchdowns right at the 1000ft-marker.
However, one should be absolutely aware of the plane's energy-status when doing such a late break, or
