I wish they were more specific: Was the mascon modeled to account for greater or less gravitational braking than expected? We have discussed this before, but we still don't have an answer. (Since I predicted less, I would really like an answer!)

Modeling of a mascon could be consistent with either result, just as the timing in the push near the apex of a swing can either increase or decrease the momentum of the swinger.
