This is may be common sense but:

My local shop has a good 8deck game and I've consistently been able to get a couple dealers to cut off only half a deck (7.5 decks dealt). When the shoe is about finished and the decks remaining is 0.5-0.75, is the TC still divided by the decks remaining? For example, if there's a RC of 6 with 0.75 decks remaining, would the TC be 8? Or just 4, as it's the last deck?

Thanks.
