Hmm...if this number is also effectively your 'move ordering percentage',
which I assume it is, it is quite low. I'd expect it to be at least about 75%.

It's strange. I did the same thing in the past and arrived at the same result.
My eval is pretty small, my movegen is very expensive yet my speed was hardly
any better. I didn't get it. I still don't.

I still don't get how some programs run 10x as fast as mine either.(Little
Goliath). What the hell do they do to make those things so darned fast?
