Not convincing.  Play 1000 games of some program with tablebase files against
the same program without.  The tablebase provides perfect accuracy, but slows
down the search.  Les Fernandez did a long experiment and found that the result
was a push -- neither stronger nor weaker.  Of course that was for the program
crafty only, so your actual mileage may vary.

On the other hand, tablebase files do make programs play much prettier chess.
And they may help weak programs a lot (if they can make it that far).
