Imagine that you are flipping a coin 100 times, and after 99 flips one side is
leading 50-49, and you flip it again and it's either exactly even or one side is
slightly better.  That's a lot of significance to ascribe to that last flip.

I think that you can say that there isn't a *huge* difference.  More than that I
doubt you can say.

But my bet is that we knew that anyway.
