currently lurk there for what must be hours on end (just because they
can).

It was paths to/from/into a depot - presumably Stratford. Unlike
Brussels and Paris there aren't any sidings close to the terminal
station.

Say 20 paths per hour between St Pancras and Stratford. Knock a few off
for conflicts in the station throat leaving say 16 usable paths. Off-peak
6-8 international, 4 domestic high speed, leaving 4-6 available for ecs
to/from Stratford. Few if any peak-direction ecs paths, but they wouldn't
be needed, only paths to bring in ecs from Stratford in the evening peak,
or take ecs out to Stratford in the morning peak.

Are you guessing about the impact on paths implied by shunting into the
depot, or are these numbers taking that into account?

The spur to the depot at Stratford is single track, between the up and down
lines, so use of the spur does not lose any paths between St Pancras and
Stratford. However, paths would be lost if you try to get trains in and out
of the depot at the same time, because of the single track between Stratford
and the depot.
