KSS Chart, page-70

Here's a thing for anyone who watches Celestrak. It seems the 4 satellites will give you 4 triangulation options to receive data from vs 1 option with 3 satellites. So does that mean Kleos have to simultaneously adjust 4 triangles to maximise the quality of the data from each permutation?
I had thought it was like a juggler going from 3 balls to 4, but in reality it may be more like going from 1 to 4.
The sats seem to be holding formation pretty well for the past couple of days. I think before it was B&D orbiting parallel to A&C, whereas now it is C&D and A&B.
Just some observations from a bored onlooker.
