I have a couple of questions regarding how the Regionals are bracketed out by the NCAA. I understand the seedings and the hosting of regionals. I am simply curious as to how the rest of the 48 teams are assigned. I did a quick exercise and looked up the RPI's of all 64 teams. Then assigned that RPI to each team in each of the 16 different regionals to come up with a "Total RPI" rating. Obviously the lower the total RPI, THEORETICALLY the tougher the bracket. Hands down toghest bracket using my VERY SIMPLE formula is the Oklahoma bracket with a total RPI of 75. Second is the Fla St. bracket with 130, followed by the Alabama bracket with 140. Clearly we're not showing the "Total Regional RPI" love to the last two National Champions. 
The "easiest" brackets in terms of total RPI are the Oregon bracket at 354, followed by the La-Lafayette bracket with 315, then Washington at 302, Florida at 283, UCLA at 240, and Arizona and Tennessee at 237.
I am drawing ZERO conclusions from the Bobbleheadbill RPI Regional Bracket formula. I actually think it was a pretty useless exercise. However, I am truly curious as to how these Regional assignments take place. Geography appears to play a role is SOME, but not all cases. And I am aware that the NCAA is motivated to keep travel costs down, if indeed my information is accurate that the NCAA picks up the travel expenses for the tournament. And I don't know if it is. And I don't think the bracketing is based on rewarding the higher ranked teams. Now, bear in mind that the RPI and coaches and USA today poll ratings do not coincide, although they aren't too far off one another.
A. Does anyone know the full formula that makes up RPI. I know that overall record and schedule strength are probably the two biggest drivers. What other factors?
B. What are the primary factors that go into determining the Regional bracketing?
