-Old habits dies hard. One of the interesting things that happens when we estimate using Team based Story Point estimates is that if, for whatever reason, we do the estimate and then follow it up with the work, and it turns out (typically) that there was a lot more work than originally estimated, then we will want to "​improve" ​the estimate ​by revising the data. Many people feel like they should update ​the estimate ​to improve the data now that they have improved knowledge.+Old habits dies hard.

-The basic rule is that you shouldn'​t update the estimate once you have "​started work" on it so you can look at all the data in your (Portfolio / Program) backlog with a single understanding of the status of the work effort - its a guess / no work. How you determine what it means to "start work" on an Epic or Feature will probably require some discussion since it may not be as clear cut.+The basic rule is that you shouldn'​t update the estimate once you have "​started work" on it so you can look at all the data in your (Portfolio / Program) backlog with a single understanding of the status of the work effort - its a guess / no work.
