300K is the baseline, not the number for 2018, so that's for sure it is going to stay at 300K if not more. Even then, CRS will come down anyway and significantly, in 2017, CRS started to drop from above 450 and hit 413, it is already in 430s right now, just do the simple math and think about it.. it might hit the rock bottom pretty soon.. I personally believe it will be way too low than 413 even at 300K.. anything above is cherry on the cake.
