Shorten the long landing
Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: five checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
Side view — the last 2,294 m of the approach.
Plan view — the first 2,294 m of the 3,624 m runway, to the same scale as the side view.
Touched down 1,872 m past the threshold — beyond the full-score zone. The arrival was smooth.
