Total disability ratings for compensation
may be assigned, where the
schedular rating is less than total,
when the disabled person is, in the
judgment of the rating agency, unable
to secure or follow a substantially
gainful occupation as a result of service-
connected disabilities: Provided
That, if there is only one such disability,
this disability shall be ratable
at 60 percent or more, and that, if there
are two or more disabilities, there shall
be at least one disability ratable at 40
percent or more, and sufficient additional
disability to bring the combined
rating to 70 percent or more. For the
above purpose of one 60 percent disability,
or one 40 percent disability in
combination, the following will be considered
as one disability: (1) Disabilities
of one or both upper extremities,
or of one or both lower extremities, including
the bilateral factor, if applicable,
(2) disabilities resulting from common
etiology or a single accident, (3)
disabilities affecting a single body system,
