Let's imagine that these personalities can increase (or decrease!) the ELO of a
program by as much as 50 ELO over the standard personality.  You might find it
amusing to run a mathematical simulation of 50 games and see what kind of a
spread you get under assumptions of +/-50 ELO.  I think you will be surprised.

Put another way, if you have a set of controls where each personality is
identical, and you change nothing but the "names" of the identical
personalities, it would not be at all surprising to see a result such as the
above.

I am only pointing this out as a reality check.  It takes a huge number of games
between peers to establish a sensible ELO rating.

Just for fun, feed your games to ELOSTAT and see what the spread is.  I
guarantee that you will find they are all completely uncertain as far as which
one is stronger (well within one standard deviation).
