To improve turn shape diagram to show twitch

Tom's video gave me the idea. https://youtu.be/-FyxoqXLkjI?si=euzYE3AKl5j8YY19.
So bad turn shape can be the result of sudden twitch at the beginning of the turn why don't we show it on the graph?

1. Keep the inside line for parallel. Afterall, parallel measure the inside ski relative to outside.
2. Use the outside line to illustrate the turn shape.
   --Use color to show the turning speed at different phases of the turn. E.g. if I twitch at the beginning, give it a red color and I know I need to improve. If I do a short turn, and red is at the apex, I know I can ignore it.
   -- Draw the angle between start/end of turn direction. C-shape will 180. Straight will be 0. It may not impact ski IQ, but I bet many skiers will find the unsymmetrical turn.
