No, fix week is fix week, each has dedicate unit and week. Floating has its own inventory pool. Don't know how many in that pool and how does it managed, so can not tell. But in theory, if it has one unit put into floating pool like this, they can only sell exact number of week on this unit, so there should be exact 10 owner for that unit in the pool. And if they put 2 units, there will be exact 20 owners.
It becomes difficulty to figure it out when the pool is shared with other different floating slots. So if there are owners that float over like week 17-25, 32-47, and it is the same unit in the pool, you will have chance more people fighting same week (in this case, week 25, and 32 to 35), and thus although some week is not shared (26 to 31), it still causes same over crowd situation.
