There probably are more draws, hard to say, I never checked.  Frank has plenty
of tournaments available for download so that you'd have plenty examples to look
through.

Probably as big a factor would be that programs will vary in relative strength
to eachother, depending on the time control used, that is some will excell in
Blitz, but others will excell in long time controls.
