We did day 4 again today and I video taped it. Praise didn't seem to help as much today with keeping him calm, I tried a few stays with lots of praise and some with none/very little and there wasn't much difference. He did manage to remain lying down for everything though, even when he heard my mom's laptop in the other room and became very alert. My laptop wasn't quite loud enough for you to hear the tasks in the video unfortunately.
