Yes 2, or ... provided that no bell makes continuous places for the whole of
the plain course.

My preference would be to define a cover bell ... as a bell that remains in
the same place for the whole lead including the lead end change ... and then
say that a cover bell is not part of the method, but we need to wait for the
discussion on cover bells for that.
