There is very little you can do to help yourself before NETVU, Area Control Sector 18 descend you to FL140 level by and then transfer you to Terminal Control (TC), Godlu Sector. Any early left turns off the STAR need coordinating with TC Timba, TC Godlu are normally sitting adjacent to TC Timba and during quieter moments, the same controller can even be controlling both sectors together, so it is far easier for the coordination to be made. Sector 18 will be aiming to transfer you to TC Godlu as early as possible, however they have to wait until around 10nm before NETVU to ensure you are within the radar range of the TC Godlu controller. Hope that helps explain it a little down that part of the Channel Tour.
