My Prediction for 2019
If regular draws happen ie: 2 draws a month then CRS will be around 447 at end of the year.
After the last draw there were around 2085 candidates in 451-600 range. And considering draw size will be increased to 3900 because another 40000 invites are pending when compared to last year intake number of 89000
and in 451-600 range average around 230 candidates are getting added daily basis which can be up and down. 230 is the max i have assumed. And around 30 profiles/perday 600+profiles
next draw size can be around
600+ 300
451-600 2085+3450 = 5535
Total 5535+300= 5830
Now if draw size is increased to 3900
5830-3900= 1930
Draw 2

i am just adding the same amount of profiles in both 451+ range and 600+ range
balance 1930 in 451 above add 3450 more profile and 300 in 600plus total is 5680-3900= 1780
Draw 3 1780+3450+300=5530-3900=1630
Draw 4 1630+3450+300=5380-3900=1480
Draw 4 1480+3450+300=5230-3900= 1330
Draw 5 1330+3450+300=5080-3900= 1180
Draw 6 1180+3450+300= 4930-3900= 1030
Draw 7 1030+3450+300= 4780-3900= 880
Draw 8 880+3450+300= 4630-3900= 730
Draw 9 730+3450+300= 4480-3900=580
Draw 10 580+3450+300=4330-3900=430
Till draw 10 if the draw lot and draw size remains similar then score will be around 450 not below it.
Its just my thought guys i might be wrong also.
