A quick analysis of profiles with 440+ entering pool in 04-24 May period:
Number of Profiles on 4th May with CRS 441 or above = 205+1116+992=2313
Number of Profiles on 24th May with CRS 441 or above = 45+127+56=228
Assuming around 100 profiles with CRS exactly 440 got ITA on 23rd May draw, number of profiles with CRS 441 or above cleared in the 2 draws in May=3500*2-100=6900
Hence, number of profiles of 441 or above who entered between 4th-24th May=6900-2313+228=4815
Daily Rate=4815/20=241/day
But, similar analysis from 16th-24th May yields following:
Number of Profiles on 16th May with CRS 441 or above = 185+871+909=1965
Number of Profiles on 24th May with CRS 441 or above = 45+127+56=228
Assuming around 100 profiles with CRS exactly 440 got ITA on 23rd May draw, number of profiles with CRS 441 or above cleared in the 23rd May draw=3500-100=3400
Hence, number of profiles of 441 or above who entered between 16th-24th May=3400-1965+228=1663
Daily Rate=1663/8=208/day
We all know there was a major influx between 4th-9th May and assuming that is due to OINP nominations, but also keep in mind that the IELTS result came out on 4th May itself, so there would be a surge due to that also. The IELTS-free draw still had about 208/day influx, so it is hard to tell.
With above, I think the next draw on 6th June will be crucial as it should show what is the influx happening with IELTS result and no siginificant PNP nominations. If it is stable in the 200-210/day region, we can hope that the cut-off will gradually come down over next 2-3 months. Larger draw size will definitely help. People saying that June 20th draw having cut-off slightly increased have some merit though, as 2 IELTS results will mean higher influx, how much higher is the question
