A route score on RouteYou is not only an indication of the 'beauty' of a route but also of the quality of a route. This quality is not only determined by the experience in the field, but also by the information provided by the author and by the way the route is presented.
What is new is that as an author you can now also submit your own route score. This is not adopted one-to-one but is taken into account along with the many other aspects when determining the overall route score.
