I think you’re right. There must be some more variables to a formula that determines max empire size. Beings that live twice as long as humans would feel that the trip to Alpha Centauri is only half as long as what a standard human of equivalent age would perceive it. This could potentially mean their empires could also be double in size at max even if they have the same disposition as humans. Therefore, as an advisor to an emperor of an interstellar empire, I would strongly encourage lengthening lifespans as the key to increasing the reach of government. The longer the people can live, the more tolerant they will be of long voyages and high latencies.
