I was wondering whether the Circle suffers from understaffing, low
train reliability or something else.

I remember reading that C stock trains are quite unreliable because of
the 4 sets of double doors per side, the doors being one of the most
failure prone parts of a train. I'm not sure whether that's right or if
it's a particularly significant factor here, but it's worth a mention I
suppose.
