There is a reason for that. In P'cola, I guess OCS had it's own dedicated chow hall. Up in Newport, everyone eats at the same place, including guests and other commissioning sources. Twice we were in chow during indoc week when a group of JROTC kids were there. I was a lucky one who had the Destroyer and he was being particularly crazy that day in chow. One of the other DI's saw how terrified those kids were and actually had to come over to stop him.
As far as PT goes. No more do you run sprints and do extra PT on carrier run days (during regularly scheduled PT) and skipping cool down stretches became a major no-no in about my third week there. One day the Destroyer tells us we'll never do a cool down circle after a run cause it's gay and a couple days later he demanded we do one like the rest of the regiment. Also, since it's written that there can be no unsupervised PT, doing the required 105 situps and pushups every night also was outlawed. That was passed down in about the third week as well. All of the PT changes happened pretty abruptly in one fell swoop after an overload in H was noticed based mostly on injuries caused by unneeded PT and exercises not listed as "standard" navy exercises. According to the Destroyer, because of the change, our class had the worst PT scores of any class he has ever had...gosh, I was disappointed.
