The avg AOR to IP time for September 2017 is the longest since at least Sep 2016 (according to the tracker). It is really hard to explain because even the applications that were delivered before XMas and summer vacation months were moving faster. Seems that the flip-flop of 4/6 and 3/5 rules are stabbing us in the back twice. Sigh...
I noticed that IP to Test Invites seems to be faster lately, hopefully IRCC is just doing more checks in the earlier phase, so maybe the total processing time won't be too badly impacted. But that is only my wishful thinking.
