The CWOP QC and MADIS are two different things. You can check what
conclusion MAIS reached from the link to that from the APRS/CWOP website.
Phillip does an analysis that adds many more other stations.

Any station that has grossly bad data will be ignored, but anything that
seems to be correct, there is no way to know. That's why it's important
to verify your own data. That should be done with other instruments.
Also insure your location and altitude are correct. If you can be sure
you are sending good data, there is nothing to worry about.

Think of the QC as a tool, if it suggests a problem, you should check your
data and confirm it's good. If there's any question, you need to find the
problem.
