This one I found odd because it violated my intuition about the score.
For money, XG rates 6/4* and 15/13 about the same. I would have
expected that if XG had a clear preference ATS, it would be for the
less gammonish play of 15/13, since my intuition is that the 3-away
player will want to steer away from gammonish positions while the
4-away player will want to encourage them. I don't have a good
explanation for this one.
