SAC-CAS difficulties scale

This scale was created by the Swiss Alpine Club (SAC-CAS) to classify the difficulties of hiking in the mountains and is widely used in Switzerland.
It has 6 levels that can be increased by half a point when there is a + sign after the value. For example, the difficulty T2+ is halfway between T2 and T3.
For each hike the difficulties are related to the path made. In some cases these values ​​are "official", but in most cases are values estimated by me.
I do not take any responsibility in case of wrong evaluation.
