Good to see you are identifying the areas that need work.
Also do a search on the regular episodes.
These are solid.
All of the episodes may hit areas that need some attention, but it is best to keep a session to 2-3 items.
We are looking for quality time spent which will bring lasting improvements. Revisit the mobilization until you stop seeing change.
Grooving new/changed movement & positional patterns takes some repetition for the stimulus to stick and become just the way that you move. It is the same with learning or correcting form with any skill. Creating a more solid foundation to build upon will prove beneficial and you will see the transfer with other skills/elements.
As you clean up sections you may find that other things are finding better positions and working things out with the other positional changes.
Keep working with it.
