Didn’t even take 12 hours. As expected, Attack on Titan’s second set ranked on the US charts, selling a little over a thousand fewer copies in the first week than set 1 did, but still putting up solid numbers.
This time, my guess (9841 copies) was only off by 8 percent. That qualifies as a pretty successful test. If the S=(6944*(R^-0.4))-60 formula can ballpark the rest of this list successfully (at least, for the ones that chart), I think we may have a keeper.
