Our team creates User Stories and sub-tasks assoiciated with that User Story. We assign the US 5 points and then create sub-tasks. I want my burndown to reflect the incremental burn-down of the US based on progress and completion of the sub-tasks. For example, US = 5 pts. that has 5 sub-tasks. Should I point each sub-task? Will that show the incremental brun-down? Really looking for the "reccomended" way.
