User Problem

Currently, the cycle time for work items will count the "latest transition to a status assigned the done category":

The start of work is defined as the first transition to a status assigned the In progress status category, and the end of work is defined as the latest transition to a status assigned the Done status category.

This causes issues for work items that are transitioned from one status in the "Done" category to another status in the "Done" category.

Suggested Solutions

If the work item never leaves the "Done" status category it should use the time it first entered that status category instead of the last transition to a status in that status category. 

Current Workarounds

You can use the work item status history table to calculate this manually.
