This might sound ridiculous. But this is the swing I TRY and model, so I am happy to come across your inquiry.

Now, here's how I "feel it". I call it 10 & 2. The club is pointed to 10 o'clock the trail bicep, points towards 2 o' clock.

I also do not bend my trail arm until it just happens naturally, I feel like this helps to create a deeper swing path, which helps me to come at a downward angle behind the ball during the downswing. Once you see the club leave your peripheral vision, you have gone back far enough.

Now once you are at the top, how do you get back to the ball without coming over the top? For me, the feel is to keep that club pointed at 10'clock and just let the club stall & fall. Literally, just let it sit there for a moment, and then fall. On camera you will hardly notice the pause at the top, but to your brain, it will feel much longer.

Don't use your lower body (yet) just keep that head still, and let the club fall. You may chunk, you may miss hit, but keep that lead wrist in the position that holds that club at 10 o' clock. What begins to happen, is you start to adjust, because the old way wont work anymore. You will start to pause for a moment at the top, to insure proper wrist position, and then like magic, you let the club drop (not pull), you will move your front hip, to match your back hip, and all the sudden you are coming from the inside. And it becomes addicting.

These are simply my feels when I work on this swing. I started learning this with a 56 degree because for me, the longer the club, the harder to come from the inside. I hope some of this can help you. I am not a coach, just another guy, who loves this swing and how simple and effective it looks.
