I start to think the PC muscle's main role is NOT to contract (if that's a role).
I suspect there is a proprioception subject of need for feedback and feedback possible either from blood-flow / energy-flow or muscle tension. Without feedback you have no idea what you do and what you feel. Switching from temsion based feedback to other methods frees a lot of things.
I agree with you that switching back and forth can free the mind. After being a way from the practice of aneros I can say with assurance that there is nothing like a good session to keep things fresh!

It is nice to see you agree... But I have no idea with what.
I am afraid I was extremely unclear (due to what I said still being at intuition stage) and you understood something entirely different.
It all comes from me wanting to express ideas not yet clear in fear of losing them afterwards.
