I think that the measure “Remaining estimated hours history” is based on the remaining estimate in the changelog.
But if this remaining estimate is based from a worklog, the date to take into account is not that of the changelog but rather that of the worklog.
How can I do this ?
Yes, you are correct. We import the remaining estimated hours history from changelog entries. The remaining estimated hours history measure reflects the time when it was set instead of the start date for the worklog. This could make some inconsistencies in reports when the remaining estimates changes could be in a different time than hours spent.
I created an improvement idea for this with a community vote. The measure is used like this by many users for many years now. We should be careful if we do any changes there. We will post an update if there will be any changes there.
