Feel a fade to bring an under-plane path back on-plane
To correct a swing whose club head falls under the plane, the speaker suggests the exaggerated feeling of hitting a fade. She says when you think you are hitting the fade the club head is much more out-to-in, and that if you feel like you are hitting the fade for a while the club head will come back to the on-plane faster. She presents it as a feel for bringing the under-plane head to the on-plane.
