What went well

Touched down at -222 fpm — a soft arrival
Straight touchdown — 3.06 m off the centreline, no bounce
1.14 G at touchdown — inside band

What held you back

Departure Taxi — peak speed in a turn 24 kt at 16 %, peak taxi speed 35 kt at 75 %, −2.91 points
Arrival Landing — Flare profile at 0 %, Threshold height at 76 ft agl was well above target at 54 %, −1.52 points
Arrival Taxi — peak speed in a turn 21 kt at 49 %, −0.85 points

Next time

Departure

Rotate sooner, bringing the nose up at 180 kt rather than letting speed build further.

What happened: You lifted off at 199 kt against a rotation target of 180 kt, rotating late in the ground roll.

Watch for: Watch airspeed and rotate at the target of 180 kt.

See Departure Roll

Arrival

Begin raising the nose sooner, at 11 ft, rather than waiting until 8.1 ft.

What happened: The flare began late at 8.1 ft, below the normal band.

Watch for: Radio altimeter approaching 11 ft as the cue to start the flare.

See Arrival Landing

Arrive slow and the sink rate at the threshold is already above schedule, the flare is short because there is no energy to extend it, and the touchdown is hard in a way that feels exactly like a late flare. Diagnosing a slow arrival as a late flare is the catastrophic misread: you respond by flaring earlier, which bleeds more speed, which makes the next one worse. The tiebreaker is threshold speed against VRef, not feel. Never diagnose a flare without it.
