Jones optimality is a criterion for assessing the strength of a program specializer. Here, the elements required in a proof of Jones optimality are investigated and the first formal proof for a non-trivial polyvariant specializer (Unmix) is presented. A simplifying element is the use of self-application. Variations of the original criterion are discussed.
