I would have loved to have been given a reservation on one of the faster
trains, but since the booking engines assume an hour to get to Paddington
from Kings Cross (maybe if I walked it)

The booking engines allow plenty of time for a slow walker to get off
the far end of one train, travel to the connecting station, then walk
slowly to the far end of the second train.

And it's 45 minutes for Kings Cross to Paddington, btw. Both Kings
Cross and Paddington also quote 15 minute minimum for connections
between trains at the same station, and (roughly) the remaining 15
minutes is the trip between.

Here's a datapoint from my trip yesterday. Time from halfway along an
HST at the Midland Mainline platforms at St Pancras, to arriving at the
Victoria line platform via the Noethern Ticket Hall: 11 minutes. That's
12 elapsed minutes less one minute used up on an errand en-route.

[There was then a zero wait for a Victoria line train, a one minute wait
at Victoria for a District line train, and we emerged from St James's
station exactly half an hour after getting off the HST. Because of the
position of stairs relative to the platforms there was very little
walking along tube platforms to be done]
