Hi there, just letting you know that as per AC rules, threads branching from top levels do count as separate threads for the purposes of AC. This does mean that the first proof linked would be an invalid AC submission since it's more than three threads, unless you specified which threads you were using from it.

Since the last proof linked contained two threads and hit the AC minimum, we'll count that as a passed AC and there's nothing you need to change about this submission. However, please keep this guideline in mind for future submissions. Thanks!
