Back on topic.....
The flexion at the end of the CSIA turns is pressure control at it's most versatile.
A rec skier can take that turn onto the steepest of pitches.
Not so for the turn that is focussed on getting maximum performance from the ski.
Contrary to the first post, there are not three possible outcomes to a turn, there are only two; 1) conservation of speed and 2) reduction of speed. Back when I was racing and coaching, Gord Brown, the chief examiner of the CSCF told us "there is no such thing as creating acceleration in a turn". Acceleration can only occur as a result of gravity in combination with proper race tactics. You cannot exit a turn faster than you entered it based on technique and/or ski performance. At the most what you can do is minimize your loss of 'potential' speed. While striving to minimize loss of potential speed through the turn, racers must try to capitalize on the opportunities to accelerate that the terrain presents through the use of sound tactics. As Gord told us, when people refer to "acceleration" what they're really referring to is the "feeling" of releasing the energy build-up in the ski at the end of a properly carved racing turn, on a clean, fast edge. It means they have minimized speed lost in the turn and have allowed gravity and tactics to play out to their maximum potential.
