[Tagging] incline default unit ?

[fly]

Hey

In the wiki [1] it is written that the default unit for "incline=*" is
"%". Still I find almost non values without a unit with taginfo [2].

Well, should we suggest to always use a unit or do we need to take care
that at least presets do not suggest to add the default unit ?

Opinions ?


Cheers fly
