What's New with CreateML discusses Repetition Counting, and says to see the sample code and the article linked to this session.
There is no mention of Repetition Count in any documentation, and it is not linked in the article related to the session, nor is it anywhere to be found in the WWDC22 Sample code.
Rumor was that the sample code was called "CountMyActions", but it is no where to be found.
Please link the sample code to the reference, and include it in the list of WWDC sample code.
