There is no number to prepare to
Every federation publishes criteria, and some publish them in real detail: what a judge should look at, in what order, and which qualities decide a comparison. What is not published is what any level of those qualities is worth, because nothing is scored that way. A judge compares whole physiques and writes down a placing, so the measurement is “ahead of the person beside you, on that night” and nothing else, and it does not carry to the next show. Objective software capable of matching criteria to numbers fixes the problem.
