Must be a piece of crap software you use.

It's the most used software for both vieweing existing operations and
for creating applications for new stations. It gives very precise
contours per the FCC rules, although I used the option to do signal
averaging for a ZIP Code since the data I am referencing to, Arbitron
listening, can be broken into ZIP Codes also.

So how are you misusing it then?

I am not misusing it. It's pretty easy to use even for a layman, and totally
simple for someone with an engineering background.

Yet listeners do not listen to them when the signal is below 10 mv/m
in your ZIP code.

Sounds like a false assumption.

It's been proven in every market Arbitron measures... in urban zones, there
is essentially no listening outside the 10 mv/m contour.
..

My listening data comes from the 4-book average for listening in your
ZIP code, correlated with actual signal strength there.

So what is wrong with your data then?

Nothing. In urban zones, there is no listening to speak of outside the 10
mv/m contour... in very noisy places like NY and LA, there is very little
outside the 15 mv/m curves.

The simple fact is that in densely populated areas in the US, there
is seldom any AM listening outside the 10 mv/m contour.

Somehow you have misinterpreted the data.

There is nothing to misinterpret. In your ZIP, no station with below a 10
mv/m get listening.

Somehow you are going wrong here. What do you think the problem might be?

I know what the problem is... you are stubborn and do not understand that
few listeners are even interested in non-local stations, and when combined
with signals that are not reliable day and nigh and which can be subject to
interference, they don't listen to them.
