The Excellent/Very Good and so on part of the reviewer comments is just part of the consideration. They also normalize each reviewers responses across all the applicants they reviewed to a score and apply that score to your application. It’s kinda behind the scenes but it’s supposed to make it so someone who is harsh on everyone doesn’t bring down an applicant. If that reviewer never gave anyone an “Excellent” then basically their “Very Good” will be considered an Excellent for that application. But it will still say “Very Good” because they won’t change their comments on it.
I think people who got mostly E with a couple or few VG scores and didn’t get it could have had reviewers who gave out a lot of E/VG. Or not, who knows. It’s just something to consider.
