CBI R4 Format

A few people told me I should be posting on this
topic. I plan on going into it in greater scope, in
private, with R4's coordinators. Also, I should point out
that I'm not trying to disparage any of our opponents.


This is the tournament format that CBI RCT for region
4 at Bucknell used:
- 12 teams were on the
schedule.
- Four rooms were on the schedule.
- These teams
were divided into two brackets (Red and Blue) of six
by random draw.
- Red and Blue played a
round-robin within themselves, with two teams in each bracket
playing each other in a sequestered round. Red played in
rooms 1 & 2 and Blue played in rooms 3 & 4.
- The
records of the twelve teams (ties broken first by average
differential) were arranged top to bottom. The six best records
went into a Gold bracket; the six worst records went
into a Silver bracket.
- The Gold and Silver
brackets played round-robins within themselves, with two
teams in each playing a sequestered round on different
questions than the non-sequestered teams used. Gold played
in rooms 3 & 4 and Silver played in rooms 1 &
2.
- The top three teams in the Gold bracket and the
top team in the Silver bracket (ties broken first by
differential) advanced to single-elimination
playoffs.

The schedule, as outlined above, presents the
following issues:
- Random draw for large fields works
more reasonably, but with a field of such a small
size, random draw increases dramatically the chance
that the two brackets will be of unequal strength --
that is to say, the average team in one bracket will
be stronger than the average team in the other,
reducing the reliability of comparisons between the
brackets. This did not appreciably happen at 2001 RCT, but
it could very easily have.
- With four rooms
running, the RCT coordinators were willing to run
sequestered rounds and two round-robins. A full round-robin
among all 12 teams would have guaranteed all the teams
an extra game to play, would have been more easily
adjustible in the event of a no-show, would have eliminated
the need for the calculations or meeting for division
into Gold and Silver, and would have taken the same
net time.
- Arranging the use of rooms such that
Red and Blue each had their own rooms, and then Gold
and Silver each had their own rooms, leads to a
situation in which one-quarter of the field only ever sees
two moderators, and another quarter of the field only
ever sees the two other moderators. Given that
different moderators tend to read at different average
speeds, and that individual statistics are taken in total
points, this calls into question the entire validity of
individual performance statistics as presented, and to a
lesser extent the value of point differentials. This can
be corrected for by dividing the individual scores
and point differentials not by the number of games
played, but by the total number of tossups heard by each
individual team.
