consensus? from me? i am a nobody in this world of martial arts, much less internal stuffs. Erick, most of the stuffs you wrote went right over my head. i am not as learned and much less in imagination. maybe your model rightly describes the process. but you have to discuss that with the experts, as i mentioned, i am a dabbler san expertise. one thing though, do you want shear stress and torque apply to the various joints in your body? how would your model work, for example, with middle of your body where, according to some of the so-called classics of martial arts, your shoulders should align with your hips, i.e. you are not suppose to twist your body to deal with incoming force or to release a force? who know, the classic could be wrong, and that's too a possibility.
