It's a nice idea, but honestly the way to get the most accurate count of who will be at what regional is to start a thread like this:

I'm an alum of 93, so I won't be going to the ame competitions they're going to. I might pop up at Midwest, Boilermaker or Western Michigan ... but that'll be decided about a week before the competition happens!!
Regardless, good thought - and thanks for putting in the time to do this!
