Hi,
I'm 459
I think they don't plan to decrease the score below 450 anytime soon.
I think they had to increase the first draw in April so that they can reduce the score slightly to 450+ range for the second April draw, this will buy time for those that will get PNP and LMIA as well as in time for when job bank will become functional.
All in all, I don't think the score is going to drastically reduce anytime soon.
I hope this is the case as I don't plan to spend money on spouse ECA just for 10points
