DK your geometry is good, I can tell. Dont worry about your noggin, this is the place for "head spinning" , my brain is normally mushed like one of those poor NASA guys riding the rocket centrifuge.

The "Out" of Three Dimensional Impact is very real as is the "Down" and the "Forward" of course. By virtue of the fact that we are traveling an Inclined Plane. Picture it from a down the line point of view, your clubhead could not be on an Inclined Plane and travel Down without traveling Out (towards the plane line) at the same time. A truly horizontal plane would have forward and out, no down. A vertical plane would have no out. So in regard to the Out, just go Down all the way and the Out will take care of itself given your plane of motion.

Thanks for explanation. Now I understand the "out" part. But it leads me to one more question: why is the on-plane swing not "cross-line" at the impact point?

Thanks,
DK
