Hello,
Actually the USCF uses a simple formula for unrated players to get to a
TPR(Tournament Performance Rating).  It is OpR+(W-L)*400 / N.  Example:
4.5-1.5=3*400=1200 divided by 6=200 + Opponents average rating(2280)=2480

This is a little low I think for CM4000 on that hardware. Perhaps you did not
give it any extra ram for hash tables.
