If nothing else, the addition of Ryan kept the show's ratings from dropping below the 4 million viewers mark (with the curious exception of one episode, "Juggernaut," that had ENT-era ratings of just above 2 million viewers).
It's not that curious. Air it on a Monday, before the show's Wednesday timeslot and have a new episode on Wednesday was a recipe for it being missed (special timeslot on a day before the normal timeslot= low ratings). With its mirror reversal, "Investigations", one would have tuned in on Monday, noticed no Voyager, then remembered the special day/time or looked to the tv guide to find it.
In the entire run of Voyager, "Juggernaut" was the only
episode to have its rerun get higher ratings than its original broadcast. 2 DS9 episodes exceeded their original ratings in a rerun with a possibility 2 others did so too (pesky gaps with some reruns). Don't have enough rerun data for TNG. No Enterprise episode exceeded its original ratings.
Star Trek was kind of on the low end. My records indicate Xena had episodes exceed their original ratings 12 times. Hercules did so at least 9 times (the series finale got a better rating in its rerun than its original broadcast). X-Files did so 13 times (all Season 1 eps though).
