Anecdotal Value Formula, Part 2

This is the formula, for all who are interested:

AV = U^P / Pr +  TA/S

Where 

U is Unexpectedness

P is Prominence (of the key figure in the anecdote)

Pr is Prurience

T is Tellability

A is Attractiveness (the Attraction of interest toward the teller in the telling)

S is Simplicity

Still needed: variables addressing circulation and humor.
