Subject: The importance of learning

The day before I released Gothmog 0.4.5, I played a blitz match (4 minutes/game,
with 1 second increment) between my engine and Phalanx XXII on my PowerBook
G4 550 MHz.  Gothmog narrowly won the match; the final score was 52.5-47.5.

Yesterday, I started a new match between the same two engines.  The only
difference was that this match was played on a PIV 2.4 GHz, and that learning
was disabled for Phalanx in the second match (my own engine doesn't learn).
The result: 65-35 for Gothmog.

Is this just a statistical fluctuation, or is learning really that effective?
Or perhaps Phalanx (a very old engine) simply doesn't play well on fast
hardware?
