Oh it’ll work without instruction. The thing with this field is that there are LOTS of instructions built into it… which you can see in the designer’s original design thread:
So — without your extra instruction — it’s working on many many elements to return you to your negentropic ideal … which means that the changes may be all over the place but also imperceptible to the naked eye… until they aren’t. For me that meant my iphone faceID stopped recognizing me and more recently my resting bite is different…
The Maxilla field is faster working in a noticeable way, in my experience. I believe that’s due to that field’s built in focus on one single bone.
