More acceleration, worse illusion. I think it would still be possible to experience it to some degree even with moderate acceleration, though - haven't seen any figures to refer to a minimum rate to trigger an onset.
Despite this mere mortal never having flown the super equipment that Centarus is telling us that he has, and despite his clear disdain for this possibility, I would have thought the acceleration of a C210 with only two on board would have been conceivably sufficient to trigger this illusion.
