It's a list of the max values available for different stats on different items. If you have an item that rolls stats at or near the max amount, the item is more valuable. It can also help identify valuable items in the AH that may be undervalued.

For example, crit hit chance is pretty sought after. If you find a ring with 4% crit chance, it might not sound like much, but 4.5% is as high as it can go, so that ring is actually pretty good.

The more stats on an item approaching max value, the more people will be willing to pay for it.

Yeah pretty much what he said. Its statistical information, it comes in handy for other things not just profit analyzing. You can use this information to help build your characters as well, this will help you determine which items can have which stats in a all in one chart. Thanks for the share.
