Can someone comment on my MADIS QC summary?

Just got the email today saying it was available... everything looks good, I think... I adjusted the barometer today to be more in line with the local airport SLP and that definite helped... just wondering about the wind I guess... I know I sorta eyeballed my direction on the thing, not sure how to read the QC for that...

For the brief 3 days I had Madis QC, I was getting the green 2 thumbs up on all sections but nothing for the wind section. I took it as meaning that they can't QC wind because it varies so much from location to location like rain does. There was a red comparison indicator however in the "7 Day Vector" display along with my indicators but that's it.

Your data looks good to me so far.  Two thumbs up, 100% MADIS QC score and a green check mark are as good as gets.  8-)

I would watch things over time as you accumulate more data.  Try not to become obsessed with chasing perfect
scores.  If you do, you'll drive yourself insane!  Everyone, even Airport ASOS sites, will fail checks from time to time.  Right now
the McCarran Airport ASOS has a big red X next to Dewpoint with a MADIS rating of 95%.  
However, if you are consistently failing MADIS QC (thumbs down) then you will want to look into the cause.

As far as your wind direction is concerned, you will want to ensure your wind sensor is aligned with True North not magnetic.

Wind is so variable and so highly dependent on siting that it is very difficult for that to match up unless you have a near perfect location. So there isn't much point in getting too worked up about that. The other parameters look good, but you really need at least 30 days, or so of data to really know how close you are matching what MADIS expects.

Very good, I'll keep an eye on it. Thanks guys!
