68強如何排名和怎麼選37支AT-LARGE - NCAA

我看了英文的維基 上面這麼寫

The NCAA has established Selection Committees for both the men's and women's
tournaments. Teams that did not win their conference tournament may be eligible
to earn an at-large berth. At-large berths are determined by record, ranking,
strength of schedule, and many other factors. A key factor in determining
at-large berths is the Ratings Percentage Index, popularly referred to as the
RPI. One absolute rule is that a team with a losing record after the conference
tournament (or regular season in the case of the Ivy League) is barred from
consideration for an at-large berth.

他是根據戰績 排名 賽程強度 RPI值

RPI值:
RPI = (WP * 0.25) + (OWP * 0.50) + (OOWP * 0.25)

where WP is Winning Percentage,
OWP is Opponents' Winning Percentage and
OOWP is Opponents' Opponents' Winning Percentage.

The WP is calculated by taking a team's wins divided by the number of games
it has played (i.e. wins plus losses).
還真的很複雜 好像還包括主勝 客勝 中立場勝等因素
不曉得有沒有包含聯盟實力因素?


排名是如何排?
這邊指的排 是不是將68隊依種子序分成16個檔次[pot] 每個檔次四隊
然後抽籤排入進四個分區?
[當然要打first four的另外排]
