Maybe Harry took a LOT of time off?
Perhaps he had a bunch of personal projects he was also working on. Hobbies and academic projects not assigned by Starfleet or Janeway. Starting with TNG, it always seemed like crewpeople could take leave and even requisition a shuttle when available pretty much any time they wanted to as long as the ship wasn't actively in a yellow or red alert situation. (Or the Federation wasn't at war, like in DS9 - and sometimes even then!)
So maybe Harry only did bridge duty whenever the ship went into an alert or potential alert situation. Under other circumstances, computer automation was able to handle managing Operations with minimal input from him - an hour or two a day at most. And Harry liked it that way because he was working on his doctoral thesis or a new design for power couplings or whatever.
To us, it seemed like he served the same 7 years as everyone else - but we only saw an hour's worth of what was going on out of (roughly) every two weeks. Maybe that was MOST of what he actually worked! And maybe it's actually someone else - Tuvok, for example - who was working full double shifts for 7 whole years whose rank we should *really* be wondering about?
For any Harry fans reading, I want to emphasize that I'm not calling Harry a slacker or anything like that. It seems to me that in a near-scarcity-free future, there would be all sorts of work time structuring options for people, and maybe Harry just chose one that gave him a lot of time for personal pursuits.
