An average of 8 people per screening

That is the link to the review of the movie, which gives the way they averaged out that only 8 people per viewing went (paid) to see this movie.

Below I have paraphrased what you will read on the Movie Phone link above:
The movie opened on 1956 screens, and "The Identical" was the only new wide release movie opening on that weekend. Its marketplace competition consisted entirely of movies that have been out for a week or more already.
Yet "The Identical" didn't even open in the top 10. Debuting in 11th place, it earned an estimated $1.9 million (well below the $5 million that some pundits had predicted), for a weak per-screen average of just $977. Which means about eight people on average attended each screening. ("Guardians of the Galaxy," the No. 1 movie for the fourth time in six weeks, earned an estimated $10.2 million this weekend at 3,221 theaters, for a per-screen average of $3,154, so after six weeks in release, it's still earning more than three times per venue as "The Identical.")
