I don't think those stats are correct. We don't necessarily collect the BG complete dates for all applicants; We update it if the applicant mentions it in their post. There is no separate column on the spreadsheet for BG Checks completed date.
The consensus was that applicants would be invited about 3 months from the BG date, which is also not true for all applicants. I am well past the 3 month mark after the BG complete date (March 9th) but still have no test invite so this theory doesn't hold good for everyone. Further, my application has been in "Test Ready" status (from GCMS notes) from March 24th.
Having said that, the time between BG complete and test greatly varies between applicants. There is no method to the madness. Someone who had their BG completed recently could get a test invite within a month while some people get test invites 4 - 5 months after BG checks are completed. So, it is hard to predict even a ball park timeline when there is so much randomness in the process.
Rest assured, once the BG checks are completed, you will receive a test invite, the question is 'when'? As a very rough estimate (given the current delays for test and oath), I'd say a sizable number of September applicants might take oath by December this year.
