Yes, I have used this procedure a few times. It takes a little more time
sometimes but I think that it has less "noise". It is very important to select
good positions. Those when it is clear that the program understand what's going
on when it "sees" the "best move" without any doubt. The problem is how to
handle the data later. Doing a simple average is very wrong IMHO. If anybody is
interested, I can post what I think it is best, I am in a rush now and I need to
explain it in detail to be understood.
