The percentage in the "Issue Statistics" does not add up to 100% because it does not round.

The percentage values are shown as integers, but are calculated using truncate, which means the sum of the percentage values almost never add up to 100%. A value of "1.9xxxxxxx" is presented as 1% instead of 2% which would be a more correct value.

Hi, @[deleted]  welcome to the Community!  When I add the Issue Statistics Gadget to a dashboard, the percentages are over 100% which would tell me there is some rounding up going on.  I did find an issue entered for Atlassian to address the percentages JRASERVER-41108 . I would suggest voting for and watching that issue for further updates.   If you want to search in Atlassian's issues, you can find their site at jira.atlassian.com
