Why do you need an old post? Most of us can tell you what you need in a sentence or two.
Somewhere I have the exact number of degrees of wash between butt rib and the rib just outboard of the lift struts. I have been using .7 degrees for decades, but I think stock wash is a bit more. And no, I don't remember which way is wash "in" - same reason I cannot remember the difference between a forward and a side slip.
It is misleading. You do not have to level the airplane when using the digital level. A SmartLevel is accurate enough even when operating around 14 degrees. otherwise, the last two paragraphs on page 3 tell you what you want to know.
