OTOH, I find most judges to be very professional and doing their best to be fair and unbiased. Besides showing, I scribe for a heck of a lot of judges - and I really think, overall, it is a very honorable profession. But... There are bad eggs, and those are the ones we really remember. Most of the bad eggs I've run into are older, and hopefully "aging out" of the profession.
I also believe USEF and the other judges should do a bit of "policing" and drum those bad eggs out. Many judges know who the bad ones are - but it is kind of like the medical profession - you never turn on your own! And to add to it, some of them are very nice people, just not good judges - which makes it even harder to "do something" about them.
And if someone wins a class of only 1 - yeah, they still won the class? So why is that an issue for Ms. Yukins? If there is only 1 in the class, it isn't the competitors fault - and that is one reason USDF uses scores instead of wins (although you can always award "win" points based on size of class). I don't care what you do, people will always figure out how to "game" the system.
In our CDS Championships, once you are champion/reserve champion, you have to move up or move on. I think it is a good rule - you can continue to sandbag it at shows, but not at the championships. Of course, it is based on horse/rider team, so you can put a different rider on the horse and go back to the same level. And I'm OK with that, since it is often a less experienced rider on a seasoned horse.
