I thought that the Aldgate bit only ran at rush hours and whilst I
can see that a last train at about 20:00 is reasonably still inside
the "travel home from the city" work hours, I can't believe that it
has a two minute frequency at that time of day.

Met trains to Uxbridge run to Aldgate at any time, not only during
peaks.
During peak hours extra trains from Amersham and Watford are added to
Aldgate service.

Two minute frequency was either because of previous overcrowding or
in response to Circle line usual "lack of drivers".

So a "lack of drivers" is a noted feature of the Circle line then?
CULG tells me that the Circle line is based at Hammersmith depot,
along with the H&C line (which presumably gets priority when it comes
to allocating drivers).

I work down there - and the Circle line service (in particular the Outer
Rail service) has been rubbish all week. One evening, at about 18:00, they
were advising that the next clockwise Circle would not be for in excess of
fifteen minutes. I suspect that they've had crewing or stock problems this
week.

"Lack of drivers" was stated as a reason for "minor delays" on the H&C
on two days last week.
