The full table of non-discounted adult fares is this one:
http://www.tfl.gov.uk/cdn/static/cms/documents/national-rail-adult-fares-jan-2014.pdf

Doesn't have fares like Brentwood-Broxbourne (eg pairs of outside-zone
NR stations on different 'lines' out of London).

Note there are 'National Rail only fares', and also 'National Rail
through fares' which are for journeys that include NR and TfL modes
(e.g. an NR & Tube through journey).

The single fare finder is however easier to query!
http://www.tfl.gov.uk/fares-and-payments/fares/single-fare-finder

However, that has £5.40 for Brentwood-Broxbourne, which is the same as
either Brentwood-Z3 or Broxbourne-Z3.

Which seems a bargain given you in practice have to go via Z3 on the
way. (If there's a Z4-only route I can't see it).

Or is this a "feature" of the Oyster zonal system already beyond
breaking point, and all it can do is charge about half what the fare
might otherwise realistically be (ie £5.40 Brentwood-Stratford plus
£5.40 Stratford-Broxbourne)???

The National Rail paper ticket is a whopping £17.50 Anytime single.
