I cannot see where you got the total fare when using Oyster PAYG as
£9.00.

A through PAYG fare between Watford Junction and zone 1 on the
Underground[*] is £6.00 (weekdays 7am-7pm) or £3.50 (all other
times). The total is thus £9.50.

You're right! I thought the WJ-Z1 journey was 3.00 - shows how often I
do it. The good news is that that means it's only going to take 5 years
for my titanium Brompton (that I haven't actually bought yet) to pay for
itself instead of 10 ;-) (As I can get it through the cycle to work
scheme it should actually pay for itself in about 3 years (although
there are always ongoing costs, tyres/tubes/brake blocks etc - I
wouldn't be surprised if I spend about 100GBP/year keeping my current
Brompton on the road)

And this would be more expensive if the passenger got on the
Underground in central London to make their way back to Euston before
7pm...

Indeed. They should, of course, use the 1.00 they will save towards a
beer before they get on the tube. It won't actually save them any money
but they'll be much happer as a result ;-)

£6 (morning through journey WJ - Euston - LU zone 1)
+ £1.50 (single z1 Underground journey)
+ £3 (post-7pm Euston to WJ fare)
Total = £10.50


And of course these calculations all shift about somewhat if a
commuter regularly takes a pre-7pm train from Euston back to WJ, in
which case they'd get charged the higher £5.50 fare twice so the daily
total would be £11 (or for a through journey from LU zone 1 it would
be £6 twice, so £12).

I guess this is probably how it works for most people which is why it's
priced the way it is. All bar one of my journey's this week have been
before 7am (actually I've been catching the 07:01 train) or after 7pm.
