Second question relates to OSIs.

Say I arrive at Shepherds Bush NR and intend to travel on from

Yes, if the time limit for an OSI expires, then it would mean that a
totally new journey was started. (I haven't double-checked that the
Shepherds Bush NR to Shepherds Bush LU OSI is indeed set at 20
minutes, but that seems more than enough time to cross the road!)

It is 20 minutes.
I did this today, largely to see what happens:
Wood Green - Shepherds Bush (Central Line)
pop up to Westfield to collect my now-repaired computer, and return to
the station in under 20 minutes
Shepherds Bush (Overground) - Harringay Green Lanes, touching the pink
validator at Gospel Oak on the way.

The journey history on a tube ticket machine shows up as:
Wood Green - Shepherds Bush (£0)
Wood Green - Uncompleted (£4.30, which is the entry charge for a tube
station)
Gospel Oak - Harringay Green Lanes (£1.30)

The first journey from Wood Green presumably timed out 90 minutes
after it started, while I was still on my way to Gospel Oak. It's
interesting that the pink reader started a new journey - I'm beginning
to think that there's no difference between them and the yellow pads,
other than the text on the display.

From what I understand from this group, the system ought to work out
where I've been, and refund me £1.90 in the next couple of days.
