I never comment in the instructional thread but as a multi-decade HOF EE, I watched your video and went WTF, I don't see EE at all. Hell , your right foot is still flat on the ground inches before impact. If you EE'd your club would hit your knee before impact because you'd be up on your right toe half way through transition like the rest of us😆.
Here we are side by side at roughly P6ish. Mine from yesterday with a 7 iron as well.
In my best Crocodile Dundee voice " that's not early extension, this is early extension!"
