If its treated as a player the AI would get to a stable and somewhat accurate matchmaker value rather quickly since it 'plays' more games of a wider variety than any real player by far. I would have no idea how to even start accounting for effects of the pilot on the crew (AI or otherwise) separately from the value of the pilot as a pilot.
However it's working now its better than the old system of counting the AI as worth nothing, I just hope they don't see the AI outside the bottom 25% mmr and decide to nerf it.
