PT (September 19th) ended a week before RCD3 (September 27th). RCD3 chapters were uploaded quite quickly, while the book descriptions for the week weren't updated, sometimes RCD3 already had the ones for the next week. IIRC, the last PT and RCD3 chapters were updated around the same time but PT not only aired a day before RCD3, it also ended a week earlier so I would say that PT is the first.
