Are you describing changing the 10-2-B grip into the C variation whilst preforming the standard wrist action? Yes, but I'm not concerned if you're performing standard wrist action or not.

Is this the rotating lag pressure point as mentioned in 10-11-0-3? No, that's different- yes similar but not the same thing. Similar in that you'd load on top and but different in that going from 10-2-B to the C variation- you're actually moving something and then back to 10-2-B during release. Keep in mind that I was just saying that experiment might help you get closer to understanding some of the concepts in this discussion

Mathew, I put my response to your question in the quote above- Hope that helps. Review my responses to your sequence- I'm saying you've got to support the load better - which changes the hand and arm locations but also requires/mandates and causes a larger (shoulder) turn. Again, I'm just free wheeling some teaching ideas here- so would be easy to shoot down any particular idea/theory that I've brought up. I'm just throwing out my feedback for you to take it or leave it- no big deal. In that regard- Lynn has a very good golf swing- take a look at the photo of him next to Hogan for the Driver- then look at the same frame of your sequence- does it look like his back is facing the target more than yours (I know you've got an iron - not the same- but that's what I'm seeing...) Then look at Lynn's video of him hitting a 6-iron- see how his triangle doesn't collapse in on the shoulder line (sure different camera angle etc)- the short side is longer than your short side because he's loading the club properly.
