 In addition, this approach leads to:
-  * Emphasizing relative rather than absolute estimates, which means that you can estimate very quickly. People are very good at deciding whether something is bigger or smaller than something else (relative size estimates), but are terrible at determining how big it is (absolute estimates). You will often see teams that can produce 20, 30 even 40 estimates in an hour with improved data and far less wastage associated with the process.
