Hi,
I think and hope I have it solved now.
Please report. 
Mr Sm0g was right about bars accuracy.
I changed the net strength scale from -3dB to -6dB steps.
Therefore the signal bars range is bigger but looks more dynamical.
The bad news, no other versions planned.
These buggy experiences learn me not to post things I not test myself first.
Unless I have a certain expectation of the reliability.
I am very sorry, but know U will understand.
