Here are some of the things we may want to consider.

Put your right hand in front of you in a Flat, Level and Vertical position, with your right forearm parallel to the ground. Have your fingers relaxed, so they are neither fully straight nor clenched in a fist. If you just let your wrist "hang" you should find it reaches the Level condition naturally.
Now simply Bend your right wrist, keeping everything else the same and remaining relaxed. Notice how, amazingly, your right wrist is no longer "Homer Kelly Level". Now is this acceptable in a full swing? Should we still call this 'Level' for practical purposes? Interesting questions, and certainly debatable, but my answer is yes to both.

Another point. Grab a club, set up as usual. The cup of your right hand should fit snugly into your left thumb and the grip of the club (if the grip was in the heel pad instead, it would not be possible to have the Clubshaft and Right Forearm in-line with a Level Right Wrist). Now take the club to the Top. Notice how the grip is no longer snug in the cup of your right hand in the same way as it was at Address. If it was the Clubshaft would be pointing way up towards the sky. Can this be a violation of 1-L-3 (there is no wobble in the Clubshaft attachment (Grip))? Is this acceptable for a human being? I’d say it is acceptable.
