well yep. In the first place i search LP in zone 370 LY from Chakchun and Coalsack site, but find nothing (but it was before we locate LP)Looks like someone tried to visualise the known flight path already on reddit Source: https://www.reddit.com/r/EliteDangerous/comments/jl8ndv/adamastors_suspected_flight_path/
the green line is certainly interesting, I wonder if there are some clues from the listening post about that long route
Also, i think Adamastor Jump range limited by somethat 400 LY. Becouse
1) They have fuel only for 370 LY in the first place
2) Carver menthioned 300 LY then they arrived in HIP 69000
