Forehand. Elbow trajectory.

[meticulous]

What is a trajectory of elbow during forehand forward swing?
Does it (elbow) move to the left or parallel to the body?
At contact, does elbow in front of the palm of behind?
How far to the right is your contact point?
Thanks.

1.Parallel to the body?
2.You start forward swing with elbow ahead,then palm/forearm accelerate and in contact roughly 5 inches in front of the elbow if more, then 5 inches, your ball will always move to the left.
3. How far to the right is your contact point? Add several inches to the length to your forearm (roughly).
