Total Participant Minutes - New data element in Zoom Reporting

Good afternoon, we noted a new column popped up in our regular Zoom reporting titled "Total Participant Minutes" and just checking to see if there was a formal definition available or information on how this total is derived?

We assume its the combined total number of minutes for each participant (i.e., Participant A joined for ten minutes while participant B was late and joined for 5 minutes.  The Total Participant Minutes displayed would be 15).

If anyone is familiar with this data element and can confirm that would be great.  Thanks!
