SJ at 13 and PS at 129 has no good explanation, if a change in methodology results in this drastic change then bestsellers are completely arbitrary and it is more about your methodology than about any actual book salesAnd there's the fact that D&D books released after the USA Today booklist hiatus tended to rank lower, which may have meant a methodology change that affected how many D&D sales were seen relative to other methods. (Fizban's debuted at #6 and Spelljammer at #13 before the hiatus, while Planescape was the first to make it after and was at #129, for example).
