Your explanation of the ABS technique would not create the clubhead speed that you are generating in your own swing.
The way you’ve defined the mechanics for squaring the clubface with your torso seems similar to this video by Gary Pinns who uses it for pitching. He is also squaring the clubface with his torso rotation, but his clubhead speed is limited to the angular velocity of his torso .
I am suspecting you are using different mechanics to what you feel you are doing.
