The elbow is down and in and driving the motion. It is not "wrist-led" because the wrist is already past the point of contact.
Wasn't talking about elbow force. It's wrist-led in that it is cutting with the forearm from an outside angle and the elbow is following wrist.
There most certainly is an "elbow idea" here. You think you can "see" an idea so easily on a video clip????
Yes. I can see that it's not in your action.
