@MaxLonged Centering. They eyeball it so you can sometimes get away with it. Any type of whitening will most likely get a 9 since its noticeable.
My umbreon was off centered and still 10'd.
@MaxLonged If its close enough you have a good chance of a 10. Some things can get over looked and sometimes theyre just really harsh on it. It's just inconsistent on psa. Theyre human at the end of the day.
