Good question,
All I could find was from a March 22 Release note below. But the metrics definition pages are not updated with this, and neither are Queue Performance knowledge pages either.
But sounds like it held time / all calls
Rather than hold time / total hold calls which is the normal avg hold time

Edit: Correction the Performance Knowledge article was updated

Does anybody know the meaning/calculation used for "Average Hold Handled" in Queue Performance reporting? Not finding information in the knowledgebase. Thanks.
