[PVRCNC] Does being spotted help?

Guys,

It would be interesting to know if and by how much spotting helps the 
spotted station.

I just ran a quick analysis of 2006 SS for my statistically meager data.

17 instances of being spoted, types of stations worked within four 
minutes of spot in each class tabulated

The fraction of stations worked in each class were compared to the 
2005 SS fractions in each class. (Big assumption 2006=2005 
participation fractions.  However, it appears that the makeup of SS 
doesn't change much from year to year.  The same stations in the same 
categories seem to always show up.  The same stations always place at 
the top too!)


Results
CLASS  SPOT FR 2005 FRA
A 	.42	.48
B	.10	.19
U	.28	.15
M	.05	.05
Q	.15	.12	

The number of A,B,U,M and Q contacts were 26,6,17,3,9 respectively.

One would expect more U's fractionally to be worked if being spotted 
helps.  The other categories should be close to but below their class 
fraction.  Big IF -- everybody is being honest and not using spots if 
their class doesn't allow it.

It does appear that U's do call in more frequently-- about twice as 
often. Hence being spotted helps.  Unfortunately, the small sample 
size can lead to unreal results.  Here the help would be something 
like 8 QSO's.  Some of these 8 could probably happen anyhow.

It would be interesting to do a more complete analysis over thousands 
of spots with hundreds of stations.
