I'd guess because Media Create and Famitsu do their adjustments publically, though in an ass backwords way. If you notice, when one is higher then the other by a large amount, the next week is adjusted as they tend to be nearly the same way off, but in an opposite direction.
Probably because the fact that their is more then 1 tracker forces them to be more clear in their numbers.
