Q: I already posted scores for a round, then noticed a mistake and corrected it. If I post the scores again, will the corrected score be posted as a duplicate, or will it update the score that was already posted? (Also asked as: "Can I post an edited score to GHIN after the score has already been posted?")
A: The corrected score will update the previously posted score — it will not be posted as a duplicate. You can repost scores as many times as needed, and each new posting simply updates the existing entry for that player, whether you post manually or scores are posted through automatic score posting to GHIN or automatic score posting to WHS.
Note: If automatic score posting is enabled, scores are posted or updated according to the automatic posting schedule, using whatever scores are entered in Golf Genius at that time. If you correct a score and do not want the correction overwritten before the next scheduled automatic post, temporarily disable automatic score posting, make your corrections, and re-enable automatic score posting once you're ready.
