George, you might keep in mind that a lot of the testing & write ups
are pretty dated. My 1970's USFS Wood Encyclopedia is word for word for
the latest publication on it that I read (2002?). 30 years ago, I
agreed with them. About 15 years ago, that started changing. Since
everyone else seems to disagree, maybe it is my supplier, but the
industry has also changed its methods & standards in that time, too. I
laid the problem down to immature trees, faster KD times & looser
grading methods. Since YP has a different set of standards, I thought
their's were more accurate. I used to be able to buy 10% - 20% over &
get all the material I needed. Now I find it's more like 50% and I
still see way more movement in service from this supposedly 'stable'
wood.
