Exactly. I remember that in FogBuzz for example (JIRA/Bugzilla alternative), they method to size is to ask people to divide work in small tasks of a few day as much and to provide who did the sizing.

When the work is done, people have to put in the actual time spent on the task. Once you used the system for some time, it has a database on size for most people and the actual spent associated to it.

So when you size new projects containing many sub tasks the system is able to provide you with a gaussian curve of probability to be finished by that time. This seems more reasonable.
