I don't ask this with any agenda, or sarcasm- I'm serious when I say "What is under plane?"

I understand if you're off plane - i.e. the clubshaft doesn't point at the plane line. I also understand if you're making plane angle shifts to flatter planes during the swing. So is "under plane"- "off plane" or is it "a flatter plane than you set up for"- I'm not sure. Or is "under plane" a description of the feel- of coming into impact too much "inside out", or does it just describe when you come inside out and block a shot. Could use some help here- it may flush out some issues or ideas I haven't considered.
Thanks in advance.

We're talking about "underplane" when the clubshaft doesn't point at the plane line (instead it points outside of it). A shift to a flatter plane angle with the shaft still on-plane isn't that big of a problem, but being flat and off-plane is a big problem. You do come into impact feeling too much inside-out and are usually left hopelessly unable to control the clubface. What feels like you "driving to the inside aft quadrant of the ball" is in reality you dropping the clubshaft off-plane and driving to outside the plane line.

Thanks Mike; your thoughts would be much appreciated.
