Documentation bug: font’s GRAD minimum seems to be −50, not −25

[MarkFonts]

Hi! in the font I downloaded, the GRAD axis range is −50 min 0 default 200 max

the left-hand UI and grade documuentation image reports it would be −25.

Yes, that seems like a front end interface bug.

Also: the example shows an icon with insufficient grade correction to make the white-on-black look the same weight as the black-on-off-white.

(Amusingly, the needed grade corrections to do this on screen are in the opposite direction of what you need in print.)

I also verified experimentally that -50 seems about right to create the same visual weight. I was pretty sure that was why I picked that value for minimum Grade in the first place.

Of course, the text description of Grade is also wrong: adjustments to Grade are exactly the same granularity as Weight — and deliberately so.
