And here is already the big difference:
I try to find a good mapping for Alpine skiing (piste:type=downhill).
The problem seems to be that for both piste:type=downhill and piste:type=skitour the difficulty is given with the same nomenclature (piste:difficulty=).
Now when I try to map an official ski route specified by the ski resort, this is definitely piste:type=downhill. The difficulty is typically not specified for these routes. (Very very few resorts nevertheless classify them with blue-red-black).
Since these ski routes are given without rating, I tag them with “piste:difficulty=freeride”. In german, the translation for this is even “off-piste”, which fits wonderfully with the route.
So my suggestion would be to rename the existing Freeride to “Exceptionally Difficult”, which is what it actually represents.
…and to introduce a new value for such marked ski routes that have no rating. Whether the designation “Off-piste” would make sense, which actually means “Off-piste without any further rating”, remains to be seen.
The photo shows the piste map of Saalbach Hinterglemm. There are several such ski routes there. These are far from jumps over cliffs or 50% drops.
