The Russian central bank expects a rate of 3-3.5%, the Ministry of Economic Development expects a decline of 2.9%. [1] Your numbers may be dated, as the expected figures keep improving. Some time back they were expecting double digit declines.

The 3.9%, 5.6% decline comes from OECD's November report, so hardly outdated.

I don't think there's much reason to trust Russian Central Bank which has strong incentives (read: orders) to enhance the numbers.
