how many teams were in from the same conference as that #52 team? seble tweaked the seeding code a while back (like a year) because of some PIT issue, which then caused the NT seeding to change (i think, people always matched the projection report if possible when that came out, and now it doesnt, and supposedly there were no other changed). the change caused the seeding algorithm to try to place teams in regions their conf mates were not in first, and then half-regions, and who knows, maybe it goes further than that. i had wondered why a team of mine was seeded like 6 spots lower than the projection report suggested, and seble explained how it was supposed to work, and those 5 spots my team should have gotten, all had a conf mate in the region - i was the 4th team in from the conf in that case.
im not sure how things might work after you already have 4 teams in a region, theres a conflict everywhere, but teams seemed to be seeded properly when i looked. but maybe theres some bug in the code, pushing that 13 seed down to a 16? or maybe there were 8 teams from the conf and all other 7 half-regions had teams in them, so they wound up going all the way to the 8th half-region? the one with 1, 4, 5, 8, 9, 12, 13, 16 in it - if thats all that was open, maybe i could see them getting bumped past all 14 and 15 spots?
