How does Diamond calculate the charts? It all starts at the comic book shop.

Data for Diamond’s sales charts – which include the monthly market shares and all top product charts – are compiled by Diamond Comic Distributors from a universe of over 3,500 accounts, comprised of comic book specialty shops and other merchant stores and buyers. The shops are primarily located in North America, with a percentage of sales also to international stores and buyers located throughout the world. The account base includes not only brick-and-mortar comic book specialty shops, but also Internet stores, chain stores, and other specialty stores.

Unit and Retail Dollar sales are calculated based upon orders invoiced and shipped to Diamond accounts during any given month, which comprises initial pre-orders, advance reorders, and reorders, minus any copies that are received back from a title marked as returnable.
