I think it's a rather ordinary result.  Even my weak, slow and buggy Gothmog
gets a similar
score.  My latest version gets 297/300 in 5 seconds on a 2.4 GHz computer.  Most
of the
positions are solved in less than 0.01 seconds. WAC is simply too easy on modern
hardware,
you need to run some harder test suites if you want to make conclusions about an
engine's
tactical abilities.  ECMGCP is a much better choice than WAC, I think.  I would
be very interested
in what results you get for Crafty at 10 seconds/position in ECMGCP.

It's impressive that Crafty is able to solve WAC100 and WAC230, though.
