Departure Taxi — beacon light off should be on, then navigation light off should be on; peak taxi speed 40 kt at 0 %, −3.33 points
Departure Roll — strobe light off should be on; Takeoff distance 6,805 ft at 0 %, −1.52 points

Top opportunity

Maintain the centreline

Departure Roll

A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.
