@timahrens @letterror So, to go back to your earlier statement regarding the weight axis: ‘Had they decided that 40 is regular and 70 is bold then our interpolated fonts would look differently.’ Would they? We’d still have axis extrema glyph designs that are conceptually and nominally regular and bold. And (user facing value) of 500 or 50 on the different scales would be the same relative distance between those extremes, resulting in the same interpolation result. The only difference between the axes is their resolution. In the one axis the user can address ten times as many integer locations as in the other.
