I know… nevertheless precision is given by a comparison of real position and measured position…
Bottom Line:
What Android reports, is an “estimated accuracy”.

highly simplified:
The sensor doesn’t get an exact position from the GPS satellites.
It gets something like a triangle.
And your real position is somewhere within that triangle.
The smaller the triangle the more accurate your position should be.
Okay… interesting. So increasing this triangle helps tracking in general. But doesn´t help to stop this little jumps uns “spider” tracks, while you are not moving… I think.
