Control chart calculations are incorrect

[Roman Kovalevsky]

Hi all. I've got a problem with Jira calculating the control chart. My goal - find out the cycle time and have a breakdown for each status.

I've got three of them (To Do, Dev&QA, UAT) and see their sum to be ~12 days. Now, let's see each column meaning:

To Do ~ 8 days;
Dev&QA ~ 8 days

UAT ~ 0 days. 

Now, how 8+8+0 might be equal to 12?

I think the issue might be in calculations behind, as I've noticed, number of issues is changes a bit, when I vary status picking. So, since there are different number of issues in each status, summarising them all would not be valid. In this case, how can I find out the initial goal - track cycle time over time periods, with the breakdown for statuses?
