I'm under the impression that 

  if A via B to C is a valid route, 

  you should be able to travel from B to C and later from C via B to A by
buying a SVR from B to C and an excess fare to extend the return portion
from B to A, 

  and the excess fare should be half the difference between the SVR from A
to C and the SVR from B to C.

Is this correct?  

If so, is this officially documented anywhere readily available to the
public (preferably on the web)?

Thanks,

As far as I can tell that information would be in the Retail Manual
Part One, which doesn't appear to be anywhere that Google can see it.

I have been told, by friendly station staff, that it is only possibly 
to do an over-distance excess in the outward direction. That is, you 
can go further than you originally meant to, but you can't travel back
beyond your starting point. That was when I asked if I could excess 
the return portion of a Lockerbie - Oxford Saver back to Edinburgh.

Aha, thanks.

Is anyone able to provide a list of the rules which dictate precisely
under what conditions an over-distance excess may be issued? I have
searched this group, and the web, without success.

Conflicting stories seem to have been put forward at different times
(such as ones that contradict the one above). In addition, there ought
to be something stopping you from, for example, buying a CDR from
London to Acton Main Line, then excessing the outward part to Oxford
for half the price difference, thus effectively getting you a single
to Oxford at just over half the price of a CDR - but I have never seen
anyone post anything that would suggest you can't do this.
