What went well

Touched down at -117 ft/m — a soft arrival
Straight touchdown — 2.80 m off the centreline, no bounce
1.06 G at touchdown — inside band

What held you back

Arrival Landing — Flare profile at 48 %, −0.63 points
Departure Roll — Runway alignment max 9.10 m at 78 %, −0.29 points
Arrival Touchdown — Touchdown distance was 701 m at 73 %, −0.19 points

Top opportunity

Work on the flare

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.
