[wxqc] Understanding the Quality Report

[John James]

I have two weather stations, and I oftentimes 
seem to get an analysis report that has the 
characteristics below:  there are errors reported 
in the summary, but the lines in question don't 
show up; I get a summary for one station but not 
the other; I get errors for one station but not 
the other. Things don't seem to report 
consistently. Actually, this is the first time 
I've had this few errors, but I'm used to having 
the report just not be consistent. I think there 
is something odd about the logic trying to gather 
report data for both stations and report them 
both in one mail message. Does that make sense?
