It's not obvious to me why reviewers are weighed more heavily. If that is the case, then for the exact same piece of code, exchanging the reviewer and the author will produce a different result. What is that automatically makes the author's opinion weaker than a reviewer, as if the former were a supplicant looking for approval?
