OK, so before I do the obligatory "well, actually" thing, I just want to reaffirm that you got the math right. But first I need to admit that I always have to google stuff you talk about in the first section of each Shelf Life (exposure therapy in this case, whereas I was only somewhat familiar with rejection therapy) and then I get too distracted to absorb the second half of any particular Shelf Life so my well is already half the size it needs to be to read any particular episode. But someday I'll figure out how to double that. Today is not that day.
So since A = πr² the π cancels out when you double the Area, so the 40% larger diameter/radius has nothing to do with π but instead comes from the inverse square law, sqrt(2) = 1.414 . Which is important because that means doubling your comfort zone still works for heretics who use square or rectangular pan pizzas!
Anyway, I only bring it up in my capacity as guest subject matter expert of telecom engineering where the inverse square law comes up all the time.
