I count only the cases where I try a move and it fails high and it is the first
move I tried at the node. I compare this number with the number of times I try a
move and get a fail-high - in other words, I divide the first number by the
second and multiply by 100. I use this metric specifically to measure the
effectiveness of my move ordering, so I'm not interested in counting the cases
where I don't need to generate moves.
