According to all the previous draws there are around 500 - 600 people in average receiving Invitations based on PNP/LMIA every draw.(remember LMIA no longer has 600 points this number might be low as well)
Assuming that and adding another 600 people with scores above 459 getting added in to the pool in these 2 weeks (Which is a maximum possibility of ppl with improved Ielts scores or students with Canadian education or what so ever).
Total is 600 +600 = 1200 (or lets say 1400 at Max)
Unless the draw size is less than or equal to 1500... lots of people sitting on 450+ should receive an ITA in this next weeks draw...
