Interesting question. I do count only positions for each ply that was searched
my logic in one second. I don't count all the positions that existe for given
ply. If, for instance in some ply existe 35 nodes, but only 6 was searched to
find exact value for that ply, speed counter will add only number six.

If you will count number of all nodes that your program find for each ply, speed
counter will be wonderful. It can go up easely three time to the number of
position that your logic is able to see in one second under the minimax.
