I looked at a specific subcategory in the kindle bookstore and the #1 book was ranked #3000 overall in all of kindle.(A kindle rank to sales calculator says #3000 overall means it sells 70 books per day)
That being said, do that mean, for my book to become the new number #1 in that subcategory, I simply need to sell 71 or more books in 24 hours?
Any clarification would be appreciated. Thanks
