We like to think of the allocation and calculation of pricing information as "semi-automated". Technology certainly plays a role in the process of creating great pricing information, but nothing quite beats the discerning eye of a human being.
Pricing information is updated multiple times per day as more data comes in from around the web. That said, just because information is being updated on a nearly continuous basis, does not mean the price of an item or items will change. If a sale wasn't made, there's no data to allocate.
