The detector refused any path over 2400 km, reasoning that past a single hop the
bearing test stops meaning anything. That was wrong, and it discarded exactly the
openings worth announcing: Nexus flagged a 6 m opening at 5477 km that OpsLog
never saw, because the spots were thrown away before any test ran.
Multi-hop Es is ordinary on 6 m — 5000 km paths are common, 10000 km happens —
and it stays directional: a second hop leaves the sector the first one entered.
So the sector test, which is what does the real work here, holds perfectly well
at any distance. The ceiling was standing in for a judgement it could not make.
The floor stays at 500 km: a short 6 m contact is tropo or ground wave and says
nothing about the ionosphere. Both are now pinned by a test.
