Afterburn, here's a diagram made by Bob Barnes. There's a ton of stuff in this diagram.
When a turn actually begins, technically, is when the edges change. With that definition in mind, the blue arrow separates turns from each other in this diagram.
However, for turns that match this diagram, something that is elusive for most recreational skiers, the skier must start doing something before that blue arrow in order to get those edges to change there. What the skier needs to do is release the grip of the old outside ski. Notice that the skier's arms start moving towards the skis before they cross the blue line. That's what "release" does.
It involves flattening the skis in some way. After the skis cross the blue line, the skier's body (arms and shoulders in this diagram) are on the downhill side of the skis.
Releasing the skis' grip before the blue line, and allowing the body to cross over the skis to their downhill side, and doing that very patiently, goes against our instincts of self-preservation.
You ask about speed being necessary to get a C shaped turn. Speed is not necessary. Even though the images of Bob skiing show him with very high angles, going fast, that is not necessary for making round turns.
You also ask about an early "edge set." The skis in this diagram are engaged on their new edges with the second frame after the blue line is crossed. This is not called and "edge set," but just early engagement.
