I noticed that, but is there a pair of other stations that could be
traversed quicker?

Not on the tube, but what about Canary Wharf/Heron Quays or West India
Quay/Canary Wharf?

You've got to get up and down the stairs from the validators to the
platform, which made me think it would take longer.

You would have to get up and down stairs at South Ealing/Northfields as
well.

I know, but not as far as on the DLR. (And the OP asked for Underground
stations, in any case). Would make an interesting day out, doing some
time trials.
