[** Nance envisions thousands of Rosity members across the planet reading this all with arms raised**] I suspect that Helgard is actually indicating is that, in reality, it cannot be raised higher with only the human equivalent of the Collar UP/DOWN dial, and that to continue higher, as some folks are doing, it requires both an additional Collar TWIST, and a counteracting Forearm TWIST to keep the palm facing "down". Is that how you humans are achieving the full overhead pose? At some point does your armpit not stop facing out (+/- X), and twist around to forward {+Z) ? Try it without doing that TWIST and I think you'll experience the collar's anatomical UP/DOWN limits that he's observing.
