So I posted a similar question to the DB forum, thinking that the afterlength (between bridge and tailpiece) might be analogous to some extent with the nut-peg part, and there are some interesting comments coming there, in particular this one...What are you saying really works? If you mean attaching the string to a different string post, as we pointed out repeatedly in this thread, that is not adding any tension or tightness whatsoever; that's not a matter of conflicting opinions here either- it's actually scientifically proven.

Extending the length of the string beyond nut and saddle may not change the tension required to produce a given note, but it does change how the string responds to deformation, including pitch change for a given bend and force required to make a given deformation/bend. Given that fingering a note is deformation to some degree, changes to afterlengths (in which I include the bit from nut to peg) MUST have a knock-on effect on intonation (longer = less sharpening) and the effort required to press the string to the fingerboard, i.e. perceived stiffness.
