Number of Chairman's Teams From Districts

[Joe Johnson]

Does anyone know where I can find out how many Chairman's Award teams each of the District Champioships get to send to the Worlds?

I thought it was in the rules somewhere but I couldn't find it. I thought that perhaps because the rules didn't explicitly say X go from District Y, etc. that the answer must be 1 per District Championships (just like they don't say anything about how many go from each Regional -- the assumption was 1). BUT...

Then I looked at last year's rules. Same silence but of course, NE sent 4 Chairman's Teams (see here) So there goes another perfectly good theory shot to heck.

Anybody know?

As long as I'm asking, how many Rookie Allstars and Engineering Inspiration Teams as well? (If you're wondering, NE sent 2 of each to Worlds last year).

Also, any theories as to why this isn't just published in an obvious place (in the rules for example?)
