Well, my thoughts are that CIO didn't do much since Friday, probably because of Friday + a day before holiday yesterday + a holiday today. I was expecting my PER on Friday, but I'm still waiting, - and more than half of other May 6 applicants (15 persons out of those who have their fees cashed) still haven't got their PERs yet either. I guess that's what CIC will be busy with on this week. And then, maybe by the end of the week, or on the next week, May 7 PERs should start coming. - in my opinion.
This looks like a Google Sheets bug - it was supposed to refresh the date list each day, according to the settings, but it doesn't do that. I'm refreshing it manually for now.
The issue here is that CIC does not actually state if they count those who have received PER, or those whose fees have been cashed. After analyzing the existing data, including data from FSW 2013, I believe CIC numbers represent applications for which fees have been cashed, not PERs received.
P.S. Cool, I have 100 posts and a rating of +50. So many round numbers
