Of course. It's a fool's errand to try and predict actual numbers from Amazon, even from their monthly charts. Weeklies are even less reliable, for many reasons.Weekly doesn't tell us much because monthly position add things up and place them. Weekly is a specific area only. We have no idea if 40 one week is less or more than the 40 of another.
My point was, what does that say about you trying to analyze hourly results? They're even more meaningless.
