RWA - pleased we have an accord!
Saturn - I cannot comment on the 'proposed' radar picture - without diving into my lats and longs and trig tables,
1) I have no idea what the range scale is between the 'red' bits or what they might signify
2) No idea what scanner angle or gain is being synthesised there
3) I see no 'Mauve/purple' to indicate moderate or greater turbulence
Depending on the distance between cells that I saw I might well 'thread the needle' as you call it - normal practice if the gap is sufficient.
A pretty picture but really meaningless in real terms.
