Do you downgrade the previous match to make room for the new match or give the new match a higher score? The problem with downgrading is you now need to reevaluate every match you rated because they were all in comparison to the top match. It's simpler to just add a new rating. Keep in mind, these ratings are the opinions of a single person and have no value beyond that.
