Incredibly bad analysis. The terribleness of this analysis cannot be overemphasized. All you've shown is that sales growth causes a decline in DOS. Duh. Also, has units in inventory declined? As prices for units decrease, inventory carrying value declines even if inventory supplies are sufficient to support rapid growth. By the same token, a decrease in the number of different models would also lead to declines in inventory and yet sales growth would be unaffected.
