No, I dont think so. Somewhere on this very forum I read the each ITA eats 1.2 space of the quota. Please keep in your consideration that maximum numbers are singles, as they are below 30.
So, in each draw consider 5% for PNP quota. Hence the calculation looks like this -
Total ITA numbers for each month = 5000 (2500 in each draw)
Used Economic immigrant quota = 5000*1.2 = 6000
Multiply by 12 months = 6000*12 = 72000
In my opinion, we will continue to see 2500+ draw every second week and at this rate it should go down below 420 by H1 2017.
This makes sense but IMO we should always go with the worst case scenario and that is why I assumed 2 PRs for every ITA. But, cheers to you for the positivity
