Wouldn't it be best to average the last two iterations since they are most
related to move ordering?  Also it would be interesting to look at the branching
factor for individual problems--large qsearch/extension positions tend to have
large effective branching factor.  I think you already have some good move
ordering stuff so that is probably not the problem...

good luck,
Michael
