Very much appreciate the trouble you've gone to Roffs but the fact remains that laterally the LHR inbound and LCY outbound tracks overlap all the time, and the adjustments I thought I was seeing weren't much to do with the various joins but all occurred around the final 180 degree turn sector.
Your plot doesn't show any of the LCY plots of course but does show the variation in LHR tracks in the area of the reported conflict i.e. around a point 70% up and 80% right on your plot (I am guessing).
Is there a Thames plot you could overlay?
As you say, its the vertical separation that keeps us safe.
Edit: Roffa it just dawned on me that you said you'd been looking at that sky on those screens for 20 years. I don't think I'd last 20 weeks. You deserve a medal if they haven't already given you one. Seriously. I'm sure they must have.
