I'm troubled by this reasoning or direction the meaning is (might) take --
as I can foresee this confidence percentage directly and
non-deterministically affecting the accuracy value when also present.

Accuracy is a purposeful fudging of the exact location.

Confidence is the best guess with a percentage of where a Location Target is.

If both are present in the reply, then the requestee gets to graph a curve
of if they believe the answer was (close to being) right or not.

Conceivably, I can see the actual location being an order of magnitude from
the location object delivered -- and then what's the point of this
exercise? Plus, the accuracy value known to the Rule Maker isn't even
correct in fudging the location delivered....
