Though note that for areas without very good DEM this tags may still provide
useful
info on short section of way.
There is a difference between gradual drop with a
normal slope and case where you have bunch of 10 cm high cliffs/kerbs -
especially
when going uphill.
Or 2m long section which is
To me, it seems that the root of the problem is that the
mtb:scale:uphill=* key is flawed.
Instead, these keys should be name mtb:scale:forward=* and
mtb:scale:backward=* . This would make everything unambiguous.
And, of course, an additional incline=up/down would be optional but very
Any good cycling router needs to use a digital elevation model in it's
algorithm, or use elevation tied to the paths somehow (such as with a
gpx track). These odd OSM tags are a sideshow.

I would intuitively prefer if you put the information about the presence
of "hops" into a specialized tag instead of making the value space
You can't really micromap until you micromap for real ;-)
More seriously, there may be no need to split ways down to the *exact* meter to
give the router a sense of the way profile with incline=*.

Oh, thanks for spotting!
This also works fine! And has some decent use already.
(and incline=up;down is not the best idea as it
- semantically applies rather when both apply at once across entire object
- is often produced by buggy editors merging ways with incline=up
and incline=down
)

There's also the tag incline=up/down which is already used around 400 times.
