I do use RL33 in the .264. IMO, similar to but less bulky than RL50. I could get ~30-40 fps more from it (and RL50) than 7828. that gain put me in the 3220-3250 ballpark.
thing is, your load seems to be a mild load but yields 150+ fps more than what I am getting with quite a bit more RL33.
that is what I would be concerned about. wildly unexpected results might seem like a gift, but still raise the red flags.
do you have access to QL?
