The first draw was 886. 
from 1200 --> 886 only 779 people qualified. ( obviously, scoring above 1100, you've to be godly! lolzzz)
Second draw was 818. 
from 886 --> 818, 779 people qualified. 
Ity means, there are more people in the 800's than between 900-1200. 
Hence, the lower the CRS goes, 4 times more pleople are probable to qualify as compared to its previous CRS Score-Rank. 
If, CIC keeps up the 779 number alive, the drop might only be somewhere in the high 790's, that's my opinion.
