For those in the pool, here is some info. For what it’s worth, I don’t know the rhyme or reason things go the way they do in the pool. All I can give you is my experience. I have 4500+ TT, 4200+ KC-135 time. Interviewed 20 Oct 17, received pool letter 26 Oct and today received CJO for a 7 May class. Hope this potentially sheds some light on things for someone. Good luck to everyone swimming.
