Hi everyone
According to the charts, it looks like CIC is charging fees / issuing PERs with a speed close to linear, so it makes a good base for estimates.
I've made the estimates - it's pure mathematics, without any guesses, based on the data we have in the spreadsheet. You can see them highlighted in yellow on the image below. They properly account for number of applications received on each particular day, work days / weekends, possible noise in the data, - everything to make the estimates as accurate as possible. Of course, there is this assumption that CIC processing speed is linear.
According to the estimates, it looks like PERs for May 6 applicants should start really soon, possibly tomorrow
Accuracy of the estimates significantly decreases for dates far into future, and
even for close dates the estimate will probably be plus/minus a week or even more, but for those folks who are asking when CIC will start charging the fees / issuing the PERs, I believe, this estimate is as precise as we can possibly get at all, given the current data
