I think you are right, based on the post a couple of days ago explaining Review Required (originally by legalfalcon):

However, from my own timeline, here is what I think happened:
Mar 18 - All stages "recommended passed" (I thought this meant I was just waiting for PPR email, but apparently not)
Apr 17 - All stages "passed" (I think this is the stage where the officer passed all the stages and my file is now ready for final review for PPR)
What I don't understand is why if the officer changed all stages to "passed", that they did not just issue PPR on that day. I am still waiting almost a month later!
Side note: In the summary table I have been posting, I am calling "met", "recommended pass", and "passed" all the same thing - "passed" - simply because a lot of people don't know which one they are under, and it simplifies things a bit.
