Having spent many years teaching in pistons, jets and [variable flare engine off landings in]helicopters I must say that Ive never heard of Msr Jakobsen's profound technique.
Although I cannot discard it as potentially valuable I can only add that surely he is putting mathematics into something we've always taught/done....using such terms as 'aimpoint', 'attitude', 'energy', 'reference point' and yes, over those last few inches a 'feel' gained through experience.
Its always amused me - and more so nowadays with 'fly by wire' jets (that change Flight Control Law in those last moments and often provide a nose down bias to help us 'feel' the flare more) - that when you ask the PF why that landing went wrong he/she as dozens of reasons often commencing 10nm out!
When you ask why a particular flare/landing went so gloriously well, they simply respond with a shrug and a cheeky grin....and maybe find some spurious reasoning like "I delayed taking Reverse a nano-second"?
