I suppose that I am being pedantic, but slope is surely a ratio. Or you can
define the same thing via an angle \theta. Slope = tan(\theta).
Maybe there should be two subtags, "slope" and "angle". Both are, of
course, dimensionless.

But if % appears, that immediately implies a slope rather than an angle,
so slope = n% seems unambiguous. Of course, 200% is valid if unusual,
not to say precipitous, but might seem odd at a quick glance.
