If you feel that being on a perceived irrelevant heading is annoying, just wait until/if/when you sample the NERC system.
Chances are you will be changing level like a roller coaster ride as well.
Currently we are accepting co-ordinations into a sector anything up to 30 mins or so from the sector boundary, Nerc average time parameter is around 6 minutes for traffic to be offered by the previous sector.
Knee-jerk reactions by the inappropriately named 'Planner' could spill your coffee!!
