You may ask the question, Do external outputs need more or less than 3 files to be processed? For all the EOs that reference more than 3 files, all that is needed to know is if the EO has more or less than 5 data element types. If the EO has more than 5 data element types then the EO will be rated as high, less than 5 the EO will be rated as average. Any EOs that reference less than 3 files should be singled out and counted separately.
