Hossa ran on a single 2.8ghz PIV for example.  I'd bet there were others.  Bruce
ran on a dual 1.4 athlon the second day.  On the first day he ran on something
different.  There were quite a few "hot boxes" present.  And I'd bet that more
than
one ran on something _faster_ than they claimed they were using too.  It
_always_
happens.
