In Response To: Comparing Extreme to Snowie (phil Simborg)

Take a simple (probably oversimplified) example, but it should make the point.

Flip a coin. Of the ten positions, the coin gets it right about half the time. Is a coin smarter than Snowie?

XG may be better than SW but something better than your test is needed to show that.
