Velocity chart false information ?

Question

Good morning,

The total of story points from the column "Engagement" are higher than the reality.

The total of story points from the column "Finished" are lower than the reality.

There is a bug OR the calculation method is not based only on my Kanban... Firstly, can someone tell me how these values are calculated ?

Thank you

I simulates several tests to understand what was wrong.

Unfortunately, I still don't know what is causing my issue.

You were right about the burndown chart : "the estimate column in the chart shows what the estimate was at the date / time a sprint commenced" and "the completed column in the chart shows the total number of points finished when the sprint has ended". However, the velocity chart does not follow this rule.

Edit : the velocity chart does not follow this rule only in my "real" project. In my sprints simulations (made in an other project), the velocity chart is correct.

Have you an other idea ?

Sometimes we modify story points values after the sprint's start.

I will create a false sprint to test if the issue was caused by these changes. If i hear anything, i'll get back to you.

Thank you Stephen
