It sounds like your analysis is based on hypothesis and not
actually using the Valentine-1.  I'd like to give some feedback based on
real life experince.  I keep the Valentine-1 in advanced logic mode
and it rarely lights up as a Christmas tree.  The only time it does
is when I am in the middle of a major shopping area and then it makes
sense that is does since there are >= 8 sources coming from many different
directions.  I have found the Valentine-1 to be consistent in its
reporting of bogeys regardless of any moving cars in the area.

I have found the directional indication to be very useful.  In one case
there was two radar traps set up within one mile of each other.  As I
passed the first radar trap, the direction indication changed.  Then
the detector was set off again pointing in the forward direction.  With
other radar detectors I would have assumed that this was due to a reflection.
But with the Valentine-1 I knew there was a high probability that there
was another trap.  And there was!

On other occasions, the directional helped discern a false alarm from
a true alarm.  For example, as I pass a source, the direction indicator
changes.  The directional also allows me to focus my attention as to where
the signal might be coming from instead of having to look all over the 
place.  When a car is approaching me from the rear with a detector
that leaks, I can tell that the signal is coming from the rear and as the
car passes me I can verify the source.  With other detectors, I would
have been unable to do this and would have had to assume that there was a radar
trap when there was none.

I've had the Valentine-1 for several months now and find its added features
to be useful and not gimmicks.
