I occasionally have to travel from Fulwel to Barons Court during the
morming peak.
I have found the cheapest way is to buy a single from Fulwel to
Gunnersbury and make sure I am by the right door when I arrive there,
so I can hop off, touch my Oyster in on the platform validator, and
hop back on the same train again to go onwards to Barons Court. I've
never been left behind yet (although I do end up standing the rest of
the way).

This is something that the recently released oyster "hack" might
support. It might be possible to record the "entry" on your card at home
before you even set off. (It depends a lot on how much the system
depends on the validators always being connected and how any audit
systems deal with a card that appears to have a missing touch via the
validator but the touch is recorded on the card)
