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.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway.
Side view — the last 520 m of the approach.
Plan view — the full 520 m runway, to the same scale as the side view.
Touched down 147 m short of the threshold. The arrival was smooth.
The rest of the report
The Kodiak 100 taxied from the parking area to runway 06 at AYDM Duranmin Airstrip in 1 minutes, covering less than 1 nm.
During the departure roll on runway 06, the aircraft used 302 m of runway, representing 58 % of the available length, and lifted off at 66 kt; ambient conditions were 25 °C with a wind of 2 kt from 333°, a cross-wind component of 1 kt and no head-wind.
Climb commenced overhead the airstrip, rising from 3,253 ft asl to 4,597 ft asl, an increase of 1,344 ft achieved in 1 minutes while traversing 2 nm.
Level cruise began 2 miles east of the airstrip, persisted for 2 minutes and covered 4 nm.
Descent started 4 miles east of the airstrip, descending from 4,606 ft asl to 2,992 ft asl, a loss of 1,615 ft in 2 minutes over a distance of 4 nm.
The final approach to runway 24 was executed from the north-east, on a heading of 240.0° at 0 nm and 113 ft agl; weather remained 25 °C with a wind of 2 kt from 333°, a cross-wind of 2 kt and no head-wind.
Landing on runway 24, which is 520 m long, was achieved with a threshold speed of 68 kt; touchdown occurred at 211 m down the runway, at 55 kt, with a firm touchdown rate of minus 395 fpm and a lateral deviation of 6.4 m from the centreline. The total landing distance recorded was 478 m, representing 92 % of the runway.
Runway rollout showed a slight alignment deviation of 10.7 m from the centreline before the aircraft came to a stop.
In total, the flight covered 11 nm, lasted 7 minutes and consumed 19 kg of fuel.
The final approach to runway 24 at AYDM Duranmin Airstrip was flown from the north-east on a heading of 240.0° with the aircraft at 0 nm and 113 ft agl, under temperature 25 °C, wind 2 kt from 333°, with a 2 kt cross-wind component and no head-wind.
At threshold the aircraft presented a good height and the threshold speed was good at 68 kt, indicating an appropriate energy state for the flare.
Touchdown occurred 211 m down the runway at a speed of 55 kt, both described as good, with a firm touchdown rate of minus 395 fpm; the touchdown point was slightly misaligned by 6.4 m from the centreline and the total landing distance was 478 m, representing 92 % of the 520 m runway.
During rollout the aircraft remained slightly off the centreline by 10.7 m, though the alignment stayed within acceptable limits.
To raise the 83.3 % score, focus on tighter centreline tracking during touchdown and the subsequent rollout to reduce the small lateral deviations observed.
