That would be if there was 1 frame per second. You need to multiply it by 8-12 per episode.

Also assuming perfect 1:1 cel production:finished product, which is highly optimistic.

I’m not saying the cel animated seasons or cel animation in general isn’t beautiful or worth doing, but as long as they’re making a commercial product at a big studio they’re going to be dealing with management having a stick up their ass about the fact that nobody else does this and it easily costs the same as a skilled storyboard team or several animators to pay just for cels.
