Flying Finn,
As you can imagine the London TMA is a mass of crossover routes and confliction points, and in your case the problem is a/c departing Gatwick heading for Northern Europe and Scandinavia. These depart on a CLN SID which routes DET - DAGGA (a point on what used to be R123 SE of Stansted) -CLN, which as you can see cuts right across the LAM3A arrival. We aim to have these a/c about FL170 or above by Dagga to help out against all the Heathrow traffic departing on BPK SIDs which are climbed to FL150. In order to achieve this, once clear of the BIG hold the KK CLN traffic is put on a heading of about 030 to avoid anything at LAM and climbed in stages to the previously mentioned FL170. This 030 heading take the a/c roughly through BRASO. So we are looking for you to be FL150 level Saber to assist the controller in achieving the FL170 for the KK outbound (if you're high at Saber it becomes more difficult for the outbound to climb through your level).
So essentially your descent profile is penalised in order to benefit the climb profile of others.
Also, we are aware that a late descent clearance after Logan can make it bloody difficult to achieve the FL150 restriction. If you can't make it, I would prefer that you let me know and gave me a idea of what you can make. I am then in a position to co-ordinate with the next controller as necessary.
