"Relativity" only implies that she might not have encountered ADM Patterson (her former maths prof, and possibly a friend of her fathers), since she was promoted (no latter than earlier that year, potentially significantly earlier)
True enough.
However, you are correct that during the confusion the events of Shattered, Janeway implies that Voyager is/was her first command.
More specifically, her first starship command. Surely any officer would have numerous commands that have nothing to do with ships before their superiors trust them with one?
Spock's first command is a much more disputed thing: McCoy says the shuttlecraft mission in "The Galileo Seven" is it, and Spock doesn't argue. How could a Lieutenant Commander fail to have commands prior to this? But Janeway, of unknown rank, is not a problem in this respect: early on in her career, she may have commanded plenty of landing parties, just as would appear natural.
On the other hand, she's equally clear that she had one or more* previous commands during Tuvok's promotion ceremony in Revulsion
Which is what we would assume of any officer long before she is given a starship. Or even a shuttlecraft.
Significantly, the command in question appears to be of finite and modest length and scope, as it sounds pretty unlikely that failure to observe tactical procedures would be a critique aimed at an overall period of vessel command. If Tuvok has complaints in that respect, they would be as regards specific missions within the command. Unless the command
is a mission, that is - say, an away team sortie or the like.
The quote also gives us an idea of the importance of the command (it's being reviewed by three admirals not junior staff officers, so it's probably important).
Nothing suggests the command would be reviewed. All we learn is that a lowly Lieutenant is dressing down Janeway, and three Admirals happen to overhear. If there were a review going on, surely the Admirals would be doing the dressing down.
Again, why make trouble when there is none? Janeway's first starship command is
Voyager, as stated. Nothing contradicts that.
Saru was still Commander in rank, wasn't he? So Pike outranked him.
Which was my point. If Captain Ransom outranked Captain Janeway (by a few years, it would seem), why didn't he tell Janeway to hand over
Voyager to him? We learned of the three DSC era conditions of which only one would need to apply - Ransom could say that he was the seniormost officer within thousands of lightyears, even though no Federation, non-Starfleet lives were at risk and no threat to the UFP was imminent. Although probably we have to assume there would be an additional condition, a permission from HQ or something. But then again, Ransom probably should start an argument about HQ being out of reach. Yet he just folds.
Which of course works as a tactic in his plan to evade, disable and if need be destroy
Voyager. But a more straightforward takeover attempt ought to work, too; nothing would be lost if Janeway refuses, nothing much won when Ransom shies away from making the challenge.
