Got the following question -
Q11) Estimation Video 3. Release Planning, we estimate the current estimate at SP and other at TShirt Sizing. How will you be able to come to a duration .
A team predicts how many story points or what size of work they can finish in a spirit - This is the velocity. Now you check the total size of Product Backlog items. When this total size is divided by velocity, you get the number of sprints needed to finish all product backlog items. It is the duration.

This calculation just gives an approximate idea of the duration, as you may add or remove items in Product Backlog and velocity is also stabilizes after couple of sprints.
