I always wondered about the "filled in" (interpolated) plot. To my observation, the orbital tracks of the satellites do not wander anywhere near +/- 22.5 degrees. It is unclear to me that interpolating the data to areas of the sky where satellites never appear has any utility.

I suppose it makes trends somewhat easier to spot -- but that could also be done just by making the dots on the raw chart a bit larger, without suggesting a continuity of reception-space that doesn't exist.

Or am I missing something?
