I saw the new ADG is 5:15 - is that per calendar day, per duty period, or per 24hrs?

Ex: 3-day NY to PHX departing 1pm Friday and returning 7am Sunday on the redeye, with a 5:45 on the front and a 5:00 on the back. Would that pay 15:45 (3 calendar days), or is it still a 13:30 like before?

BTW, the same trip at B6 would pay 10:45 and there are a ton of them (and other similar ones as low as 10 hrs) in Open Time. Though a lot of them are even worse - 10pm Fri departure to arrive 03ish in the morning, 1hr drive to hotel, then redeye back - all for 10hrs.
