Ignore the system info for a moment ...
The signal strengths are more detailed than a simple pass/fail.

Are you still receiving your channels from 118° (HD locals I'm assuming)?

It looks like there might be a problem with the "System Info" screens.

Trust the "Point Dish" signal strengths - 70s in to 80s would be better numbers there, but channel reception is the goal. Do you know what your numbers were the day it was installed? Have they slipped?

Plus dishes are not easy to aim. Neither are superdishes. I'm not sure which I'd say is worse at the moment (but I prefer the open design of the Plus dish - less places for spiders and wasps to live).

The plus dish is new enough that it is hard to find an experienced installer. The little tricks that installers eventually learn that go beyond the instructions can be helpful. Reaiming MIGHT give you better numbers on 118° - but you might also find a new way to throw off your aim.
