It's unclear (to me, at least) that "use runoff to reallocate the last place option votes" would be the best method here. And if such a three-option ballot were to take place, choosing (and explaining) the ranking/counting method to be used would be a crucial element. In particular, "reallocate the last place votes" could lead to quickly rejecting an option that is hardly anybody's first choice, yet is everyone's second choice (or preferred fallback if they can't have their first choice). That doesn't seem like a desirable outcome.
