He expressly brings the test back to a subjectivity in that an accused is to be judged on the basis of their age, experience and understanding rather than on the standard of a hypothetical reasonable person who might have better knowledge and understanding. Nevertheless, the test remains "hybrid" because the credibility of the accused's denial of knowledge and understanding will always be judged against an "objective" standard of what you would expect a person of the same general age and abilities as the accused to have known.
