I think he might be maths teacher , trying to prove theorems by assuming values of variables .Based on the record i can see from myimmitracker - about 65% june applicant got PPR. 2017 average time from AOR to PPR was 100 days but in 2018 it is 175 days.
almost all PPRs record in myimmitracker in last few weeks had wait time 180+ days.
anyways i am not ruling out that I am not in SS, i will wait till i get my ATIP note. but i am surprised by your confidence.
