Using any setting other than 0 can, theoretically, lower the overall playing
strength. Randomness basically adds a random positive or negative amount to
every legal move at the root. This can result in the non-optimal move being
played. The higher the randomness value, the worse the overall playing strength,
all else being equal.

Also, the randomness value of a personality has nothing to do with the opening
book. It only affects the search.
