# The max_variance is hard-coded here at 12% to leave us some
# margin. Testing has shown this normally to be in the range
# of 2%-8%, but it may be as large as 11%.
# Variances are expected since this test does not account for
# metadata. The hardcoded limit here is empirical and should
# not be construed as deterministic.
