Since I am new to posting here if this sounds confusing I apologize ahead of time. If the head cannot remain perfectly still during the swing and even Homer ( if I understand him correctly)basically says to do the best you can to keep it steady, isn't this somewhat a case where "seems as if" produces the feel of a still head that we are trying for even if it is not really still.

That's how I see it paspilot. Science is great, but we don't swing in a test tube.
