You really can't predict anything with this. Take for example I recently read on a thread here that someone called and was told her security check hadn't started, the next day she got final decision.My friend who applied May 26 2022 called ircc and they were told that the application would not be finished processing until October 26, 2024.. the status bar in their gckey account shows 100% complete She got her pre arrival and eligibility letter March 22, 2024. It seems the processing time for refugee to pr applications are now at 29 months.. I want to think it’s because they just recently got the eligibility letter which why they have to wait so long
You call and they only give you the timeline for processing as posted on the website and sometimes it takes more or less time.
You expect that they go month by month and out of nowhere, you find out people who applied after you got their PR already. Or that every month it's people who applied at the same time, only to find out the files haven't moved/been worked on for a couple of months.
There are many examples, but in short nobody can even slightly predict.
Best thing is to just wait and pray for the best and hope for luck.
