I thought cross over is when your scope doesn't point in the same direction where your barrel is. In theory, the scope is, it's just 2mm offset.
You can still have a scope central over your barrel's bore but not be parallel. Depends where you measure it from.
What I'm saying/asking is it enough that it's just parallel? Opinion seems to be divided.
