I'd entered my HA8 5LW postcode as my start and 'Royal Albert Hall' as
my destination. Why was JP so dismal? What could I have done for a
better suggestion?

In the advanced options, set it to use bus only. It will then come up
with exactly the route you had expected:

Walk to Holyrood Gardens
Take the Bus 302 towards Kensal Rise
Kensal Rise Station Stop: KH
Take the Bus 52 towards Victoria Bus Station
end Kensington / Royal Albert Hall
