I've been studying the trackers and reading through multiple comments on the trackers and this is what I figured.
1 - Usually, its safe to say that the first process is clearing medicals. You tend to go into R10 once your pass medicals. I think this seemed to be the case when you clear medicals in 30 to 45 days.
2 - Medicals are now taking more than 2 months to clear. I have seen FSW-O on 75 days and still not passing medicals. However they all seem to be having additional schedule A document requests. Hence, their file is surely being worked on even though they have not cleared medicals.
3 - This also explains why many people who pass medicals off late move from NBG back to NA in the matter of days. Probably their R10 was already done and medical was the only thing pending. Hence, the moment medical passes, they move from NBG to NA in a matter of few days and then their file moves to the A11.2 check. This also explains why once they clear medicals, the files are moving at rocket speed and many are getting their PPR in 35 - 45 days.
By the way, I am on Day 63 and still not cleared medicals.
