Let me do this again (from scratch, even). The following are the number of records that have the listed elements, out of 289,294,984 records processed, as of 1 January 2013 in WorldCat:
700 $4: 14,229,291 or 4.92% of the total
700 $e: 9,904,536 or 3.42% of the total

What percent of the total do the total occurrences represent?
And what number of unique records have a 700 with a $4 or an $e?

How often, on aggregate, is the 100 or 700 $4 or $e used? Since I've parsed a lot of MARC records, I can tell you. Not much (and the inconsistency of the $e makes this even less useful).
I can tell you exactly, as of December 1, 2012 in WorldCat:
Total number of records: 287,229,344
Total occurrences of a 700 field: 80,731,356
Total occurrences of 700 $4: 24,908,408
Total occurrences of a 700 $e: 14,117,538
