Oh yes. My conclusion is that when I match the two
programs again I know with 95% certainty which one is
going to lose in the long run, if either.

Well, among those 2 engines the winner is the better chess
player. Unless you define 'better chess' player as something
else than that which will win the most games.

It doesn't say a thing about performance vs something else,
but I find it interesting to compare different versions of
the same engine. If I fiddle and it suddenly plays significantly
better than the old version, that is a good indication that
that setting is better even vs other programs/humans.
