It all corrects itself in the long run. Heck, for a few years when there were little to no other choices just about every new Stern release was hitting top three within a week of its release before dropping well out a couple of weeks later. Even with owning and playing all three extensively, I will readily admit that having a title like B:TDK edging out AFM and TZ even for a couple of weeks is just absurd and not to be given serious consideration.
The only people that rankings negatively affects are those who are easily influenced in their purchasing decisions by short term hype.
