Sierra Area LCR: Aggregate

Each unit is only counted once, regardless in how many sub-areas it is needed. In order to come up with an aggregate deficiency, where applicable the deficiencies in each smaller sub-area has been accounted for (based on their effectiveness factors) toward the deficiency of a much larger sub-area.
