There is a lot of spread in that bell curve. For example, there were about 25 of us who interviewed on the same day (April 13, 2019) and subsequently received CJOs. From there, there was a 2 month spread between when the first guy got a class invite to when the last guy did. I don't know the entire rack and stack methodology, but I am fairly certain the last 4 of your SSN plays into it significantly. Being in the pool 6 months is not out of the normal flow right now.
