There's no evidence that CRS will rise that much but even of it does it'll go down in the very next draw and continue falling.
There is no hard evidence but one can assume that the number of ITA's may be close to 4000 with a higher cut off because of new factors. If you look at the previous ITAs, it seems as though 4000 is limit per draw. Now the Minister may already know what range (with those new factors added) will amount to a ~4000 ITA. It could be that yes, it rarely made a difference or it could also mean persons who were just short of the cut off are now in it because of the new factors leading to an increase in ITAs per a higher range too. We'll just have to see.
