A few observations:
1 - The top 2 did not lose any games.
2 - The top 5 drew 40% of their games among themselves.
3 - The top 5 finishers used 4-way AMD64 machines.
4 - The middle 6 used 1-way AMD64 machines.
5 - The bottom 4 used 1-way P4 machines.
6 - The bottom 4 got zero points against the top 5.
7 - Diep got only 1 draw and equaled most wins (7) of Junior.
8 - Diep had a perfect score against the bottom half of the table,
    but was -2 against the top 5.
9 - Jonny got the top score among the 1-way machines doing it the
    hard way by drawing the top 3 finishers, but only going +2 against
    those that finished below it.
10- Crafty had the fastest hardware combination by using 4x2.4Ghz AMD64s
    and also running in 64 bit mode.

A few questions:
1 - Which if any of the above observations are part of a significant
    trend over the last few computer tournaments?
2 - Which programs besides Crafty ran in 64 bit mode?
3 - A few of the programs changed hardware after the tournament
    started. In which rounds did these changes take place and from what
    hardware to what hardware?
