Rock climbing and bouldering tours are classified e.g.
Sierra from 5.2 to 5.15c or
Fontainbleau 2 to 8c+.
As you advance in your climbing experience you achieve higher
grades and learn new movements, new aspects of already known skills and
new combinations of them. Moreover, there are route setter certifications for
local, national and international level and a proper organization e.g. (http://www.routesettingassociation.org/)
When a route setter creates a new route with a wished level e.g. FB 6c+ - he or she probably has some movements and some skills in mind.
Where does the route setter know from which movements capabilities and skills are assigned to each grade?
Are there some general catalogues / guidelines which movements or skills are necessary to master a certain grade?
