You are correct my friend, most PNP Outland applicants have got PPRs from Jan, Feb AOR groups, and currently they are working On March Folks, your file is at NDVO if you are a PNP Outland applicant, and NDVO is working extremely slow these days, now they are issuing PPRs to FSW Outlands from March 2017. You are also correct about the time of issuing PPRs in 2017, only very rare cases are stuck from Jan and feb, average people are getting PPRs in less time than this.
NDVO does thing of switching its concentration from one stream to another, in the beginning of September, they were concentrating on PNPs, now on March FSWOs.
NDVO sometimes opens a batch on time and sometimes skips a batch in between and reopens it later on. So there is no way to predict their working my friend. Only option is to order GCMS, and wait. GCMS will tell you exactly what checks have been cleared in your file and what is your next due date. Though NDVO rarely keeps the due dates, if you are more than 180 days in process, you can also raise a CSE, but they mostly give stupid replies like "be patient" etc. rather then any useful information.
So it all depends on when someone opens you file there, otherwise files are mostly gathering dust.
