Meter ratings

I've been blowing some dust off my brain about meter sizes and how they are determined. I have some demand load books from Mike Holt and browsing through them I noticed demand loads can be higher than the meter rating. So below is the one I'm speaking about. I was thinking you would have to go to the next up in meter size if the demand load exceeded the meter rating. Not the OCPD but demand load. The main ocpd is the next size up from the demand load but doesn't the meter have to be up-sized in the case shown?

check the size of se conductors you can use in a resi 200 amp service and what they are actually rated for. I think that will clue you in with this.

whoops, meant 225 amp

Is that a #6 neutral I see on that chart? Does NEC still allow you to downsize neutral for "balanced load"?
