44% Eastern (28 teams)
38% Central (24 teams)
13% Pacific (8 teams)
6% Mountain (4 teams) - but AZ schools are only in the MT half the time per se
And here were the population numbers you posted...
Eastern 47.00%
Central 32.90%
Mountain 5.40%
Pacific 14.10%
Alaska and Hawaii 0.60%
Perhaps if the numbers posted were to mean something it would mean that some CT teams should be removed from P5 so they can add some in the PT or ET.
