I think there's a lot of truth to this. I've known quite a few wood graders over the years, and although they were consistent, they had their own approach. One guy was always attempting to upgrade my wood, so that he could charge me more
...while others were being more objective.
One thing for sure is that as the quality and availability of wood declines, the bell curve which they use to grade it conveniently follows, until what is now considered "master grade" is what was AAA ten years ago. Master grade typically has even grain, perfect quarter, consistent color and stiffness, and some special aesthetics going on, like totally even coverage of ribbony medulary rays...
I got to see some master grade German spruce from the 1960's once, some wood a friend has, and I've never seen master grade like this....ever.
I did not know wood could be so good, and I've had some amazing wood in my hands.
You see this with Brazilian rosewood on e - b a y. People trying to pass complete garbage off as high grade Brazilian. Some of it is rosewood, but it's not even dalbergia nigra, but something else. Very rarely will there even be a quarter sawn set on there, yet many of these vendors claim it is master grade, or "special stock." But that's e - b a y. Most large scale tone wood dealers have a far more objective way of grading, still, it is slowly sliding south.
