@vilas you are describing the landing, and the opinions of my more experienced colleagues (albeit with PW) mirror your words. That is below 30 ft. If you cut the thrust on NEO to idle “IAE” style, the plane’d come to a standstill at around 10 feet.
Two different phases there.
The effect of decaying wind from which GS mini protects us is something that tends to happen below 150 ft, down to 25 I would say. Due to more lively thrust (whatever that is) the delta GS buffer needed reducing to 1/3 in order to prevent excessive energy at flare for the NEOs. That is my explanation of the article.
