When running a PRIZM profile in ENVISION why is the index for a segment reporting 100 when there are zero counts and zero base counts?

As a rule 0/0 in profiles will yield an index of 100 instead of 0 because an index of 100 is our baseline, indicating that segment presence in an area reflects its presence in a base area, which is the case when there is zero count and zero base count. An index of zero is meant to reflect situations where there is no segment presence in an area but that segment does exist in the selected benchmark.
