My previous estimation for CRS distribution pool and cut off was for 3nd Sep. So, let's see if there will be any difference in cut off score range if I add one more day to the calculation.
After 20th Aug draw, with 3,600 ITAs issued and cut off 457, the CRS score distribution would have been:
601-1,200 = 0 (3,600-337=3,263)
451-600 = 5,345(8,608-3,263)
441-450 =8,189
Note: As cut off was 457, it means that the 5,345 profiles left on 451-600 range are those who have score 451-457 only. Let's assume that 5,345 are distributed equally to 451-457 score range. Thus, it makes 5,345/7=763 profile per score.
So, by 4th September, the score distribution will be approximately:
601-1,200 = 630 (42x 15days)
451-600 =10,055(5,345+4,710(314x15days))
441-450= 8,399(8,084+315(21x15days))
Suppose that from 4710 newly added profile from 20th August to 4rd Sep, 2,355(50% of 4,710) are of score 458-600 and the other half are of 451-457 score range which will be distributed equally through. So, it makes 2,355/7=336 profile per score.
So, if CIC still gonna issue 3,600 ITAs the cut off score will be approximately 455-457
3,600 minus:
-630(601-1200)
-2,355 (of 4,710 from 458-600 score range)
-615(of 763 from 5,345 in 457score left on 20 Aug)
with 3,900 ITA, the cut of score will be aporoximately 455-457.
3,900 minus:
-630(601-1200)
-2,355(of 4,396 from 458-600 score range)
-763(of 5,345 in 457score left on 20 Aug)
-152(of 336 in 457 score added after 20 Aug)
Cut off score estimation for 3,900 ITAs changed from 454-456 to 455-457.
So, it means that 300 increase in ITA numbers from 3,600 to 3,900 won't make any difference in cut off score according to this calculation/estimation.
