We have recalibrated our bouldering grades! This means that the difficulty of the sets has not changed, but the grades we give the problems are different. Even the circuits are staying the same difficulty, although the tags will show changed grades.
The process behind this decision was a lot more involved than may be immediately apparent. Read on if you are curious about different grading systems, want to know why we use V grades and understand the reasons behind the recent changes.
