There is no specific source yet but for information kindly visit open data and immigration press releases.If this is the case then yeyyy .
Can you post the source of this?
Also, information about months were received to me by applicants who received email from IRCC stating they are targeting 2 to 4 months to process application. This was then verified using immigration tool that also see trend of applications moving faster for June or July onwards.
Score going down to 400 is my own estimate.
I hope this will make things clear.
