The database file has been updated to 85 storeys (from 82 previously) as I've finally seen images that explain how the new floor count has been derived without changing the height of the building. The explanation is that the number of double-height floors at the base of the building have been cut but two, so you get two more floors there (being taken up by the hotel), while they are also including the rooftop terrace level now as a floor as well. Each of the penthouse units only has a tiny amount of indoor space on that level, essentially just enough for a powder room plus landings for the circular staircases and ensuite elevators, but hey, good enough.
