There are 7 draws only left for this year(Assuming 2 per month with November having a regular draw and a PNP/FSTC draw).
Assuming the number of ITAs left are 89000(3k more than what was issued last year) - 54700 = 34,300
Out of these 34,300 approx count of ITAs, 700 or 800 will be allocated for the PNP/FSTC draw. So roughly we have 33,500 left. Spanning this count of 33,500 across 7 federal draws gives us 4780 ITAs per draw to meet their annual target for this year.
As IRCC is constant with the number of ITAs to 3750, going by the same number for the rest of all 7 draws -- They will not meet their target. Thus there will be back to back draws if draw size is not increasing to meet their targets. We might see a back to back draw even next week ... who knows but it will happen for sure ...
