This test started failing on us for no apparent reason. Example: Ic95f7b0 https://integration.wikimedia.org/ci/job/quibble-vendor-mysql-php72-docker/11469/consoleFull Output: "test control group is about 25% (30.8%)" It appears like the bucketing is not really done based on an actual random number generator, but based on a hash that contains the session ID. If this session ID is not really a random number, the hash might not be random enough as well, but be skewed towards one or the other direction. We propose to take the normal distribution into account and change the narrow +/- 10% margin to +/- 20%. Change-Id: Ib163f1de4f9cff27aaf8dbc81189315142ff0d8a |
