Yes,  this all makes sense to me now.  I wrote this before I had your info
regarding crafty and time control.  But I did go back to Crafty 16.2 and found
that it misplayed a endgame using <EGTB> so I just scrapped all the 16.2 games
and also the 16.4 games and I'm starting over with my test.  I've never seen
such strange results as I'm getting now.  Sometimes when I start a series of
games Crafty seems to give Junior and Fritz fits.  Then the next day I start
anoter series and Crafty gets blown away.  It's like it has two different
personalities.  All I can do is combine all the results and see what happens.
