EdZ, I like your post. Could you explain further, the
exception, that Hogan used. Did Hogan use rotating lag
pressure? I have a hard time seeing the rotation in
pictures of his swing. Thanks, Donn.

In photos where he has the 'cup' (double wrist action), you can see it (page 63 5 Lessons, although not a good angle)- pretty much a given if you have a 10-2-A grip and a cup at the top, especially with a startup swivel.

All of those combine to a very open clubface, which let Hogan fire as hard as he wanted through the shot and never fear that he would close the clubface. The same thing with a steeper plane angle would risk a high right side and a pull or pull hook IMO. In a sense, Hogan almost used 'getting stuck' to his advantage (see page 91 and 95) - which the flatter plane angle allowed, but a steeper one (ala Byron or Watson) wouldn't.
