There has occurred on this forum a time for many posters to learn the rudiments of reading nrs. We all have had some very good lessons from a vairiety of disciplines on this very site. Every day someone posts how much they have learned on this forum. All are very thankful when thy post.
The first thing one should do is get some coaching or practice reading nrs. Geez, thats important dd IMHO
You have just described in your post, a bad day on the forum and we've had a few.
A basic understanding and an analyzation are two very different forms of getting educated and I'm sure that those of us with basic understanding will still be able to come to a conclusion.
