I have found it to be fairly accurate and to be sending me more "outbided emails" this week then any other.
But then I always bid what I believe the domain is worth about 1 month before it drops and if someone outbids be that does not change my mind. I wind up getting about 25% of the domains I bid for which usually happens to be the domains I want the most.

That is exacly why I don't bother with the BS of NameWinner. Bids are out of hand. You see crappy four letter dot coms going well into the thousands whereas I know people here and elsewhere that will sell very similar domains for 10 times less.
