Regarding this question, in the explanation, for climb correction it is mentioned that +2900kg is added. Why has this been added if the starting mass is 210,000kg? On the table for climb correction (Annex 033-049) the row for M0.82 under the "210" is a dashed line and not 2.9.

Consequently I am only adding the descent correction (1000kg) and getting a final answer of 173,200 which is the marked correct answer (albeit with the 3 and 2 switched around!)

Can someone clarify please I am not missing anything here?
