here is something for you to consider.. from Scrivener...
In the whisk, he advises Nellie ( his wife ) to sway in the OPPOSITE direction as suggested by the rev. techn.. he states.. " That it sets the poise on the back foot for lady ", also , retaining her head in a closed position.
he also discounts CBM for man to the degree prescribed.. he calls it "only sympathetic ".
As we can readily see, one of the greates theorists ever, disagreed with standard principles of execution, which only goes to show.. theories are opinions.. they work for some , and not for others.
Technique in some cases, is there to be challenged . It is not an issue of agreement, but a matter of choice .
