In setting the fractions, I note that generally the fonts have an absolute symmetry in the general dimensions, even at the cost of setting up different kernings. In the image that I attach (this is the Adobe Jenson Pro) it is noted that, for example, the 3.numr and 7.numr have a significantly different distance from the slash.

Now: is it better to aim for a homogeneous kerning or to guarantee the same amplitude for each fraction? And in the latter case, is there a specific technique to gain rigorous results, or simply a shrewd appeal to kerning?
