In the process of studying for L3 teach exam and wanted to start a conversation/dialog regarding some terminology.
I know what a "retraction" movement is in the "textbook" sense of the word.
I also know that when we are asked to do "retraction" turns or "extension/retraction" turns the examiners are looking for an "active" retraction or pulling up of the legs under our body.
In the bumps for instance we "retract" to absorb an oncoming bump.
In the powder, we "retract" to get our feet out of the the crud or powder so we can either turn our feet or change edges.
In a medium to long radius turn we might retract to create an edge change and cross under move to get our COM moving down the hill or get the skis to a high edge angle early in the turn.
The question and dialog I am interested in is where else is a "retraction movement" used?
Is a lightening of pressure at the apex or exit of a turn in order deal with chatter on ice a form of retraction? however...(fill in with your thoughts and why please)
