(c) Add +0.712 to value recorded in (18) above (let value recorded in (18) above
be 10.741).

return loss
(21) Divide value recorded in (17) above by 2. Invert sign and add to value recorded
in (18) above. Record sum as return loss.
EXAMPLE B: If value of (17) above is +1.425
(a) Divide +1.425 by 2 = +0.712.
(b) Invert sign of +0.712 = -0.712.
(c) Add -0.712 to value recorded in (18) above (let value recorded in (18) above
be 10.741).
