Hhmmm...How does she see it?

Well, to be honest, it really depends on how green 'green' is.
By the time a timber gets to me it has usually been felled and sawn for a few days, if not weeks. And depending on the weather it may have already started to dry some.
Thus it gives me a bit of an advantage when I go over my timbers.

Spiral grain can be detected in the tree before being sawn, but that is different from spiral check. A timber with spiral grain wouldn't even make it to the saw.

Spiral check happens mostly in straight grained timbers, and can depend on such factors as speed of growth (varying yearly growth can cause a timber to dry in some funky ways, fighting against itself), or how the timber has been sawn.

I don't know exactly how I do it...I just know wood.

But I'm sure I miss some, as well blush (*disclaimer*)
