L2 activity 8: 1000 steps
Individual · green / gentle blue · large turns stepping ski to ski without a break, through the edge change too. Switch to the mistake to see big diverging steps that stall. Drag the large view to orbit.

What the examiner looks for
Passing · Large turns while stepping ski to ski continuously, including through the edge change; narrow tracks; lifted ski parallel to the snow.
Cue · “Small quick steps, never stop.”
Key movement · The legs flex and extend alternately, with the lifted ski staying level. Watch the lifted-ski height and the two knee angles trade places.
Lead-ups · Stepping on a traverse; 1000 steps on the flats.
Mistake · Big diverging steps that stall: the tip opens away, the ski lifts high, and both feet stop on the snow at the edge change.
Fix · Small steps, skis mostly parallel after the first one.
A simplified, illustrative model on the same turn model: the right way takes about 6 small, parallel steps per turn; the mistake takes 2 big diverging steps per turn and stalls at the edge change. Angles, loads and efforts follow the shape of real technique but are not measured data.
