Were not done, but we surveyed the literature to come up with this. At more than 2 rpm visitors might need a day or so of adaptation but residents should be no problem at all. Paper probably still a month or more to first draft.

NOTE: with training (repeated specific head motions) people have adapted to 10 and even 23 rpm in experiments.
