I Just Drive.
Not too sure about this one to be honest! However just remember what the EAST controller is trying to achieve. They have to get the CLN Departures from Stansted and Lon City up to FL210 through the inbound Stansted/Luton/Cambridge routing IDESI - LAPRA - ABBOT and Norwich inbounds IDESI - BANEM to leave CAS.
The IDESI - LAPRA track is beneficial to the EAST controller as it gets the inbounds out of the way of the outbounds and so you can give climb/descent. Once the outbound is through the inbound then you can turn the inbound (normally before LAPRA) direct to ABBOT. Now the track miles fron ABBOT to a 10 mile final for RWY23 at SS is not a lot, so by slowing your descent rate down (remember you must do at least 500 f.p.m.!!), you could increase the miles flown as you have to be dog-legged to get the height off.
Hope this helps, but you're more than welcome to come and see as it is easier to explain with a radar in front of you than it is just through words.
