For the unlimited 9, you'll want to post only your best score for the week. If you shoot a round and think you'll be unable to beat it, then go ahead and report the score to be on the safe side. If you do manage to beat your score, then just report the new lower score.
I just don't want people submitting 10 times for every round or submitting 35's and 34's after they've already shot a 32. Stuff like that. =)
