How will that improve reliability with the present service?

Not at all, if single track doesn't cause reliability problems.

I am not actually proposing doubling, I am rejecting the "reliability"
excuse for cutting services.

The point is not that the services on the MHE branch are unreliable in
themselves, it's that having an irregular sequence of trains coming
from the northeast reduces reliability at Camden Town, messes about
with train frequencies through central London, exacerbates problems on
the line and leads to greater system-wide delays.

....and according to the article originally quoted, the service frequency
to High Barnet will be increased as a result of the MHE changes, which
means benefits to the four other stations north of Finchley Central.
