On the Release Planning page, the total number of story points included in a Release is calculated based on the story point equivalent of the Initial Estimate (t-shirt size) assigned to the features. Is it possible to have this calculation based on the Refined Estimate if it is present rather than the Initial Estimate?
The release planning is based on the Initial Estimate. Unfortunately. it can not be changed to user Refined Estimate.
There is the help link the explains how the Release Planning board functions.
