I just read the new changes to the knockout rules, and found that the scores would be submitted as ordinary MARP scores, with a note in the description that the scores would be counted in the competition.(posted 9252 days ago)If you already have a very good score at a knockout game, it could be extremly difficult to submit a score at all, since you have to beat yourself to submit.
A better solution would be to separate the knockout scores from ordinary MARP scores by using a prefix like in the tournaments.
