Janeway Factor

The Janeway Factor was an informal term used by Captain Braxton with regards to Captain Kathryn Janeway of USS Voyager. Braxton considered Janeway's meddling with the timeline a major annoyance, and coined the term to describe it. 

One of the occasions he listed included when Voyager traveled back to 1996 to stop Henry Starling, and then left Braxton on 20th century Earth.
