Last yr between mid april to october end there were only 750 ITAs issued. And lots of people started saying that 480 is the new 450.Immigration changed. The job points for example. People who didn't have a job offer were always at the bottom of the pool. Yoy can't compare a 430 this year with a 430 last year.
The score never gone below 450 at that point and people had the false thinking that CIC controls the points it is not the case if CIC had anything to do with the points they would have never drawn people with 413 points.
Its all game of how many people to invite if from now no new people come up no one improves their scores CIC will still draw and scores will fall.
