dvdr,
The traffic movement figures are calculated by looking at the number of aircraft that work one or more controllers at the defined unit. An aircarft is not counted twice if it works an TMA controller and then an approach controller. Approach only movements will account for probably less than 1% of the total figure at LTCC. However, the number of approach controllers at the unit has a huge effect on the movements per controller score.
My point was that simply comparing movements per controller is not necessarily the best way of looking at it.
