Is this the "isolated incident"?

After a second read of the
post by Captain America I had pointed the last week, I think its assumptions are essentially correct (and some of my previous conclusions,
here and
here, conversely wrong). Look at the diagram below:
fore needle pointing
down =
negative fore deflection =
diving position
fore needle pointing
up =
positive fore deflection =
surfacing position
conversely:
aft needle pointing
down =
positive aft deflection =
diving position
aft needle pointing
up =
negative aft deflection =
surfacing position
In other words: move both needles to the black scale (down) for diving, move them to the red scale (up) for surfacing. This is exactly how stock 3d diveplane gauges (in command room) work, and how UI diveplane dials should be modelled
Another way to see it all, is that the "thick back end" of the fore needle (not represented in the above picture) and the aft needle (identical in shape to the former), represent the aft profile of each diveplane.
