Assuming external-soft-error-proneness and x-x and uni-directionality, we can think of a "space" of possible simulations we might live in, thought of as quadrant 1 of an x-y plane where x represents "how many seconds pass in our simulation for each second in the real universe" and y represents "frequency with which soft errors occur in the simulating computer". Different experiments would rule out different parts of that plane with different probability.
