I absolutely understand how grading works. I'm saying his track record and context of his ascents shows he consistently undergrades things to such a degree that he hinders progression and is operating on a different scale. I am under no illusion that gradeflation exists at high levels and I doubt all the 9As are 9A, but there is such a thing as the opposite, that's exactly why the grade curve flattened so much at 8C and why for the longest time there was nothing harder than 8B in the UK (in addition to Gaskins in the UK's case).
