could you draw a picture of how the right elbow could be in front of the ball at impact with a driver?

I don't have the inclination to draw a picture but imagine Playing the Ball opposite your Right Foot by opening the Stance and/or Plane line (Mostly, just the Plane Line). This would be Typical of the Right Arm Swinger. Go to the range and hit balls this way. Close the Clubface a little. Easy Peasy.

I don't think that the Right Elbow Aligned ahead of the Ball at Impact is practical or feasible enough to Pattern the Components with the Ball located forward in your stance as with a Left Shoulder Centered Swing.

But it's obvious that, if the Center of the Stroke is behind the Ball, then during Impact, the Clubhead would be traveling Forward, Up and In, not Forward, Down and Out.

Of all the "Topped" shots mishit everyday, I wonder how many are caused by mistaken Stroke Centers?
