I haven't seen the letter, but know what you're referring (and there are references to it in this months MD, John Romano feature on Britt Miller). The powers that be mandated a 20% reduction for the ladies. This has caused lots of confusion as to what is the standard by which one should reduce herself.... i.e., if Iris is considered the standard since she wins the big shows, is Iris minus 20% the new ideal? Is it referring solely to mass? Does it take into account conditioning?
Since it is not clear, and this is a subjective sport, after all, some ladies I've talked to at the top nat'l and pro level are all pretty much of the attitude that they will create the look that most pleases themselves b/c who knows how the judging will go.
