Challenge/Response or Challenge/Response/Response is a read and do checklist. Things happen in a specific order and one at a time. These checklists are used most often for non-normal or emergency checklist.

The Do/Verify checklist allows flows and you proceed at your own pace. The checklist then is a checklist to check that all tasks on the list have been accomplished. This type checklist is most often used for normal checklists.
And "done, done, done' is no response as it does not identify what has been done. Switch positions should be called (off, on, etc). The person running the checklist then verifies that not only the response is correct but also the switch is in the actual position. More than a few airplanes have left the gate without sufficient fuel in spite of the checklist response on the CVR stating required fuel on board.
Your Captain is defeating the checklist and its purpose.
