Multiple realities
(covers information from several alternate timelines)

"Starfleet captains are like children. They want everything right now and they want it their way, but the secret is to give them only what they need, not what they want."

– Montgomery Scott, 2369 ("Relics")

In the history of Starfleet, many officers held the rank of captain or held the title of captain while commanding starships.

According to Travis Mayweather, Matthew Ryan spent more time in space than most Starfleet Captains. (ENT: "Fortunate Son")
