Blip, whilst I'm sure you fell Mr Jacobson has a point...the technique you describe complicates what in reality is a simple yet misunderstood maneuver.
Heavy 747/777/767/757/737 behave VERY differently to the lightly loaded versions...therefore a fixed reference point for the correct flare height is only a small piece of the puzzle.
The key component to a reasonable landing is the ROD that the aircraft experiences on touchdown...and this is as variable as the surfaces and surface conditions that we all land on.
All that the Jacobson technique proves is that he understands geometry far better than the average line pilot
