OP, you'll fall short of your 2850 if you keep your flights as is.
FWIW, I received the following on SK A fares last year:
CDG-ARN: 1850 (or 925 at 100%, instead of 959)
CDG-OSL: 1684 (or 842 at 100%, just like
Knobbgb)
It's funny, I didn't realize that I received fewer miles than I planned until I saw this thread and checked my account.

IIRC, the really short flights get 1200 minimum for SAS Plus, so adding on ARN-CPH/OSL should put you over the top.
