Repetitions
If only 2 repetitions are present, either leave as-is (e.g. “Hey, hey.”) or add a counter (e.g. “Hey. x2”)
If more than 2 repetitions are present, add a counter (e.g. “Hey. x5”)
Make sure to use an uncapitalized “x” when using a counter.
If, for whatever reason, it’s not possible to add a counter, just discuss with the subber on how to better handle that line.
