I think the scores will be back and forth between 420-450 throughout the year. And there are broadly two reasons for this:
1). Job offer points going down to 50 and for Managerial Level 200. This has been the biggest reason for low scores. Just see the trend from November 2016 onward.
2). Backlog prior to 2015 is more or less over. I again reiterate, that people getting scores between 400-450 isn't easy. Unless you have Canadian education or Canadian work exp, its extremely impossible to go above 450.
But again, CIC has failed all reasonings that we have ever made
