Re: riker's choices
Yes, Memory Alpha says it, but where did they get that information? I can't find any dialogue in the episodes to support the 22-year-captaincy idea.
I have no idea where it came from. Memory Alpha is what I've always referred to when I need information. I'd suggest contacting one of the webmasters to find the answer to your question.
