I really try and avoid getting into these how to land discussions, however I just have to comment on this subject.
If you look at the far end of the runway after the flare to the level attitude you will never ever really be able to judge your height above the runway...period.
This nonsense came into use about thirty years ago when someone decided this was a good way to teach.....
...sure you can judge the nose attitude looking way ahead but you can not accurately judge your height above the runway.
When I was teaching flying two things were very common with pilots.
(1) Climbing like a roller coaster chasing the airspeed.
(2) Looking way to far ahead during the latter stages of the landing, resulting in the inability to accurately judge height above the runway.
Accurately means about six inches from the wheels to the runway.
