Easy.  Normally you seed the field, then the top half plays the bottom half
in round 1.  After this, you maintain seeding order, and players with equal
scores play in the next round.

With accelerated pairings, you pair as though the top half were paired against
the bottom half in round 0, so that in round 1, the top half of the top half,
plays the bottom half of the top half.  IE you reach stronger competition one
round earlier.  But in such events there really are 6-8 programs with real
chances to win, another 6-8 that are fairly close, and then the remainder that
are strong but a ways from the top.  Even figuring out who belongs in which
of these groups is difficult.  And if the seeding is dong wrong, it _can_ affect
the final result, since tie-breaks favor the higher seed player...  because he
has been paired against better opponents...
