I presume its the line to Moorgate you speak of? In which case usage
will become zero come March next year when it gets disconnected as
part of the Thameslink 3000 works.

No, I was thinking of inner curve northbound from City Thameslink; the
line to Moorgate strikes me as being straighter. But one other
mitigating factor is that he trains are going over that more slowly
(because all trains stop at Farringdon) than they do around the
Liverpool loop.

OK, I hadn't clocked that as a particularly tight curve, I'll look out
(or more likely listen out) for that next time I'm on a train up that
way. Of course once all the works are complete then the 'new'
Thameslink service is going to involve a very frequent train service
through this central section, with trains travelling faster courtesy
of ATO.

You're right about the line from Farringdon to Moorgate of course, not
least because it basically shadows the not very tightly curved
alignment of the Circle/Met line here. The first photo on this page
shows the line in question:
