The monthly sales estimates at right are for comics shipped byDiamond Comic Distributors, the largest comic-book distributor in North America.
Diamond publishes "indexed" sales figures, in which it keys orders for all comics it lists sales for to a single comic book (usually Batman), with one "order index point" being equal to 1% of that title's orders. We use the actual Diamond final orders from titles accounting for more than 25% of Diamond's Top 300 to approximate what an order index point equals each month. The result is applied to the Diamond charts to produce the estimates seen at right.
