I dont think it is a matter of staggering decks. Heck, split level decks would make it even hared fit 895 of them into the ship. Though i cant find the source where the wiki got that number from. Going with the height of 202cm, adding space for a little headroom, floor pannels, ceiling panels etc....lets say a minimum of 2.6 meters per deck. Thats 2,327 meters, more than twice the height of infinity.
