That number is ill-defined because its author didn't leave any procedure of evaluating this number. If Bowers has in mind a very solid definition for BEAF, then he just wasn't specific enough when writing it down. The point is, with all the definitions Bowers made, this notation is too ambiguous to say that these numbers are well-defined.
