Tom Randall Instagram – In this carousel Slide 2 shows a couple of graphs we looked at whilst working on eGrader that really help to explain our main goal.
We tried to include all of the danger spectrum from Blue = the equivalent E grade of a bolted sport route (remember UK sport routes were originally graded with E Grades) to Red = extremely dangerous.
As you can see, the two graphs line up almost perfectly from E1 to E7, from where the current average E grade (as things stand) begins to drop off. This is the ‘compression’ we’re discussing and why it’s so contentious to propose new E Grades, seemingly irrespective of the sheer difficulty involved.
Looking at the top graph, there are a couple of interesting examples to take note of. These are Equilibrium and Rhapsody. Both of them were “first of the grade, and have become considered benchmarks for E10 and E11 respectively. They also happen to be much more consistently aligned with the lower E Grades than other routes of E7 and above.
eGrader helps us to align the upper end E grades with these benchmarks and the rest of the E Grade spectrum, creating a more consistent progression from grade to grade.
