Good post as usual.

I experience the process somewhat differently. I also get whole-body improvements each time I do my exercises, but I'm able to release a specific part of my body at the same time. It's not one or the other in my case.

For example, when I released my lower back a few months ago, that spot started to progressively lose its tightness over time, each session adding to the one before. So each time my spine straightened. But each time my jaw also released forward, my bite slightly changed, my posture improved, my general symmetry too (though in a really subtle way), and the way I naturally move changed, etc. Same thing back when I started with my 3D intraoral craniofacial release (my "thumb-pulling" approach).

Although I do find that the flexion point moves over time. For example, if I did the craniofacial release now, I believe the results wouldn't be as pronounced.

In terms of bone movement itself, I believe it might be caused by neuroplasticity.

My hypothesis is basically that what you're doing is releasing the soft tissue so much that at some point the body needs to change its movement patterns, structure, and overall biomechanics. Which leads to more prominent changes in appearance and bone movement. But maybe the potential was there a while ago. The nervous system just wasn't given the signal to change. It might be that by changing the soft tissue so much externally, the nervous system eventually gets an indirect signal or is "forced" to update its compensation patterns. Then it mobilizes the soft tissue that's been ready for a long time, taking the bone with it.

In my case, I might be doing both at the same time. By focusing on more efficient movement patterns, neurofascial connections, and my breathing, I'm releasing the soft tissue and updating the neuronal map simultaneously. The soft tissue gets exposed to a new pattern piezomechanically and is released, but the nervous system also says, "Hey, this movement pattern is more efficient. Let's use this instead." So the changes become apparent faster. There's probably a two-way feedback loop happening, too, between the nervous system and the soft tissue. The new biomechanical pattern itself also passively maintains the unwinding and neuroplasticity.

Of course, this is only possible thanks to a system already in a more plastic state and an unlocked bite that allows the body to instantly learn and adapt. Otherwise, I believe a locked bite would instantaneously "fight back" from its local soft tissue and prevent the downstream soft tissue from being as flexible and responsive. It would continue pulling and reverting any improvements pretty quickly (this is why most people need to practice a movement a million times before it gets learnt, while nowadays I personally upgrade the software on each session).

The Reviv keeps the skull's soft tissue in place and prevents the bite from collapsing when it is freed, acting more in the long term.

In the long scheme of things you may still be unwinding the soft tissue faster than I am. But I might be seeing the benefits faster. Or maybe I'm progressing faster, or the benefits are just more noticeable. Who knows, hahaha. It might also be that, as you say, the difference is just because our compensations are different, but I'm not inclined to that response.

Anyway, this is a long comment hahaha

I've been thinking about this lately, as I do less direct unwinding and focus more on movement patterns, breathing and fascial connections and literally have to set aside time each day to document my many changes in my journal 😂
