Assuming ITAs issued in each draw stays constant @ 2750 and draws happen every 2 weeks, the February and March CRS cut offs could be somewhat like below (assuming current average intake continues):
Feb 7 - CRS 442
Feb 21 - CRS 440/441
Mar 7 - CRS 439/440
Mar 21 - CRS 438/439
The above predictions become void in the below 2 scenarios:
1) If number of ITAs issued in each draw increases/decreases from the current threshold of 2750.
2) If the gap between consecutive draws are more/less than 2 weeks.
Disclaimer: I have no insider information and all these are predictions based on multiple variables and the average intake data I am using is based on pool composition from Nov 2017 till Jan 2018. So, using these predictions for decisions regarding applying for OINP, etc. should be your own responsibility and I am not responsible for your decision.
