Only Count January Bowl Games
With all the extra Bowl games, look at bowl games in January only. It's not the best cut of good and bad Bowls, but it's simple and makes a realistic good vs. bad Bowl barometer. Also, I'm not a BcS fan, so I don't think BcS only games is as good of a measure (think playoff).
In January, your conference's better teams are playing, so the Bowl record is reflecting how good the top of the conference is. It's great to send 10 of 12, but this shows dominance over depth.
I don't have the exact numbers, maybe that could be added? I've done it the last few years and it again shows the SEC is even more impressive!
