i only went on two different floors, so i dont know if there was anymore, but it is a big place
the question how long to make a model..... ages!! when a model was being made theres loads and loads of cleaning of the model, it also depends on what materials were being used as theres sanding, spraying drying times etc to all take into account, so i dont think there is a straight answer although if a press mould was being used and something straight forward like a morph was being made, i guess a few in a day
