Disclaimer: I work at Google, but not in Analytics. I'm not sure that the comparisons here are apple-to-apple. The first graph compares "visits counted in WP Engine Blogs" versus "Sessions counted by Google Analytics". How does WP Engine Logs count visits? Analytics uses a specific deduplication scheme for sessions -- e.g., a user visiting twice within 30 minutes only counts as one session. There are ways to explain how visits would show in logs but not in analytics, but I find it difficult to believe that 2/3 of these blog visitors are using a tool that blocks requests to Analytics.
