[wxqc] Data questions

[saf]

I am noticing that the data being reported on my mesowest chart is no longer at even intervals. http://www.met.utah.edu/cgi-bin/droman/meso_base.cgi?stn=c4759<http://www.met.utah.edu/cgi-bin/droman/meso_base.cgi?stn=c4759>.  It is showing data at 10, 15 and 20 minute intervals.  I upload my data on 5 minute intervals and I think the mesowest previously reported on 15 minute intervals.  
Question:  Is this normal?

My uploads at  http://www.findu.com/cgi-bin/wx.cgi?call=CW4759<http://www.findu.com/cgi-bin/wx.cgi?call=CW4759> are listed as expected at 5 minute intervals so the variance doesn't appear to be caused by my equipment.  

Question:  Will this inconsistency in recording frequency have anything to do with Quality checks?

Question:  Can the Regression Analysis from the http://www.met.utah.edu/cgi-bin/droman/meso_base.cgi?stn=c4759<http://www.met.utah.edu/cgi-bin/droman/meso_base.cgi?stn=c4759>
site be used to provide any valuable information for adjustments on my weather station?  Example, my daily quality checks show my current barometer settings passing but the Regressive chart shows me slightly high.  

Last Question:  Is there a chart to show the correlation from headings to data in the Daily Quality Reports?  I have a good idea of what it is trying to tell us but two lines of headings and two lines of data seem subject to interpretation errors? 
sample:

 DATE     UTC      SITE  *   ALT    * POT TEMP *  DEW PNT *    DD    *    FF    
                           *   (MB)   *  (DEG F) *  (DEG F) *   (DEG)  *   (KNT)  
04-MAY-2006 Errs    CW4759 *   0/96   *   0/96   *   2/96   *   0/96   *   0/96   
04-MAY-2006 Smry    CW4759 *0.24(0.81)*0.41(3.13)*-3.2(2.39)*7.96(100.)*   1(1.89)

First line..........Errs
 
Date - no problem, easy to understand
UTC - Will show UTC time for errors when listed in detail, no question (Yep, I've had errors show up too!)
Site - no problem
ALT - Altimeter shows zero errors of 96 comparisons
POT TEMP - Temp shows zero errors of 96 comparisons (ok, I'm new, what is POT Temp?)
DEW  PNT - Dew Point show 2 errors of 96 comparisons
DD - Wind Direction? shows zero errors of 96 comparisons
FF - Don't know what this is...

Second line...........Smry

(MB) - Millibars? expected .24 (observed .81) assuming this is the difference between what the analysis expected and what it observed? How is it summarized?  Average error over 24 hours?
(DEG F) - Temp? - expected .41 (observed 3.13) analysis expected a difference of .41 but saw 3.13?
(DEG F) - Temp? Dew Point? - -3.12/2.39 says my readings are high?
(DEG)  - Wind Direction 7.96/100 - I have no idea what this means
(KNT) - Wind speed in knots - 1/1.89, again, no idea

If there is a location available to us to answer these questions, I haven't found it or noticed it presented to others who have eluded to these questions.  I hope asking in this way will be helpful for all of us.



Thanks.........Steve
