Are you looking at random flights or the flight you are on? If it is random flights then that seems normal as changes roll in. If you find a pattern then good luck! The only flight you need to start watching is the one that you are on and my experience of this is to start watching a week out then about T-72 you might start seeing some changes (or not of course), and then about T-24-30 the seatmap will become "solid" and seems to stick. What I mean by solid is that you do not have the pseudo seatmap any longer. But checking random flights between now and then, even on the same route, is pointless imho.
