Crafty _is_ better at longer time controls.  Not necessarily better than Rebel,
but better than itself.  IE I don't believe it plays very well at blitz, vs
other programs.  I know it plays better at longer time controls as I watch the
games on ICC, FICS and chess.net daily, and there I play plenty of games vs
other computers.

If I gave the opponent sole power to choose the time controls, you would find
that _most_ operators would end up playing me at the fastest time control they
could.  Because they do better there. I've watched this many times... so much
in fact that I even stopped playing computers in bullet because I was losing
most of the games, and I didn't want to use those games for 'tuning'.

If you want to find out where _your_ program is strongest, put it on ICC, and
then hide and watch.  Make a graph (after a year) of all the games you have
played, and figure out which time control you are playing the most games at.
That is your weakest time control.  The human operators are 'smart'.  :)
