If the skater does not strike off to the next spiral perpendicular to the axis, it is a flaw. You are supposed to get power from every count. You should expect control of the 3s. The edge you step to after the 3-turn edge should be placed down on a real inside edge. The ability to place the 3 correctly is a marker of control and edge quality.
Regression is an error.
Lobes should be lobe-shaped, not U shaped or heart shaped. The step between lobes on the F3s is really hard. Don't expect great beauty on these steps. Look for a complete weight shift so that the weight is all the way over on the long inside edge, not somewhere in between the feet. Edge quality includes the ability to hold the edge to the turn, and then to the axis.
