Why would they release such information? The point of this contest is to get people to fly more. If the top team knows that they're the top team, they might curtail their flying. This is very much like a closed-bid house sale... if you know what other people have offered, you'll only offer enough to beat them; if you don't know what they offered, you'll offer as much as you're comfortable offering, which could be substantially higher. The same is true here - if you knew you were the top team, you might not try so hard to win! It's not in UA's interest to release that info.
