A reference, not part of my story
The grading scale was not part of the journey recorded in the book. I did not measure the opening, assign myself a type, or use a number to decide whether the process could work.
Readers encounter several competing scales online, so this page once tried to translate them. That created false autobiographical precision and pulled the site back toward clinical explanation.
What a number cannot tell you
A grade can describe how far a foreskin retracts at one moment. It cannot diagnose scarring or a skin condition, predict an outcome, or tell you that somebody else's routine is appropriate for your body.
My honest starting point is simpler: I could not retract when soft or erect. The book follows what happened from there without pretending I had a clinical classification.
If you need a clinical assessment
Use a qualified clinician rather than a diagram or this website. The value of my account is what the experience felt like and how the year unfolded—not the ability to grade another person.
