Based on your first screenshot you already have remapped f@mask attribute, no need to deal with dist

So you can directly bind "mask" attribute in the shader

I definitely wouldn't try to set restlengths directly, there is so many different constraints

I usually just match the areas of uv panels to the real geo and use it as input for the Vellum Rest Blend
Which more or less sounds like what that paper seems to be about

This of course is best when uvs represent the real rest panels like from marvelous

also make sure that the noise is not cause by the geo itself as it can be the case with meshing etc...

since there are some randomly popping yellow details in your shader suggesting some unstable uvs or other issues coming from the geo itself

you can also try freezing one frame of the geo and have slow camera movement to see if the noise and jittering persists to better judge if it's really shading noise or not
