Sorry, I wasn't clear about this, especially in the title.
This is in direct reference to times when you raise and are reraised (
Jay argued for calling the reraise against a particular type of opponents and I think he is right if his read is good), and in indirect reference to just calling a raise if no one else is likely to come in.
Obviously, raises that keep QQ in and knock Ax out are great. This analysis is for a fairly rare situation, since almost all the common ones are not even close (so why bother with the math?).

PS Also note that this is essentially the best size stack (=pot after call) for the call, any smaller and you are pot committed by a call, and bigger stacks should get in more as the (usual) favorite and a raise better defines the opps. hand.
