Before the last draw there were about 6800 people from 451 to 600 and about 274 for 600+. After issuing an ITA for 3600 people the total falls down to about 3695 people. If the draw takes place on the 21st, and even if new people joined the pool (451-600 range new addition would be approx.1500, and 601-1200 range would be 300) still the lumpsum total would be 300+1500+3695= approx 5500. The upcoming draw would remove another 3600 candidates or even more which leaves about 1900 candidates (mostly ranging from 451-460). SO, in about a couple or more draws, the CRS has to fall down considerably.
