There are two options from Finsbury Park to Cambridge: +London[1] and
Not-London.

You could always use the CLive Feather Discount, and buy a ticket from
Finsbury Park to London Stations...

That was an alleged bug in the v1.0 routing guide.

Today's routing guide says the only map to use for such a ticket is EE
(initially I suppose it may have said WA[1]), which reveals just two
mapped routes (which are also direct trains, so the map isn't adding
anything) to Kings Cross and Moorgate.

[1] You can understand how that might have happened, WA is in other
respects a much more logical map to choose than what's in effect
"secondary ways to get from London to the North East".
