I'm not lying. It held 1st for at least a few days. Tomb Raider XB1 peaked at 2nd or 3rd during the same sale.
I don't find it hard to believe that the PS4 outsold Titanfall when it was in stock. At the time, amazon was one of the few stores that had them available, whereas Titanfall is available everywhere. The PS4 still currently sits 1st for sales in March and Titanfall is 3rd.
That's why I question if Amazon does some weighting by revenue (I've always wondered this btw).
Ok, by recent armchair estimates in this thread the latest PS4 slog at Amazon may have been 20,000 units? That and your estimate of 166/hour in prime time?
If Titanfall sells a mil shouldn't we think it can do more than 20K at Amazon? especially given how front loaded software sales are? A ton of those Titanfall sales should be happening on day -1, 0, and 1. as well, PS4 sold out it's allotment over 5+ days.
One possible kink is I think Amazon credits a sale as when the preorder is registered (they did this with PS4 preorders counted as sales in June, etc). So maybe that could have skewed a lot of day one Titanfalls over a greater range of days.
Still even at that, I would just assume Titanfall would outsell PS4 hardware around release time.
I dont have a definitive answer, all I can say is "one would think".
The mechanics of Amazon's rankings have actually been scrutinized for a long time. Authors want to know how they work because they affect book sales, for example. I remember a long time ago I remember reading about them in relation to books, and attempts to understand what makes them tick. If an author can move his book up the rankings, it will sell more, etc.
