Analytics attended count not matching Attendance by Performance report

Good morning! I've run into another instance of Analytics not matching a standard report. I'm trying to pull total attendance numbers for the run of an exhibition, along with access area scans into that exhibition (which, sadly, don't appear to be available in Analytics). I started with an Analytics widget and got an attended count for the time period of 11,434. If I run the Attendance by Performance report for the same time period, I get 11,641. Both are restricted to the production season and the same date range. The numbers are close, but any thoughts on why I'm off by about 200?

Thanks!
Anne
