31. Recall that our criterion for indistinguishable models is that their (Formula presented)’s do not differ by more than 1% in the range (Formula presented)
32. It is worth noting here that although (Formula presented) is interpreted as a contribution to the vacuum energy which has (Formula presented) offsetting (Formula presented) from zero and allowing V to have negative regions can yield (Formula presented) while the field is still dynamical. For example, if (Formula presented) is the kinetic energy of the field), then (Formula presented)
