    I got here when I attempted to pause a test that had not completed an "integer" of weeks. As in it had a fractional week's worth of data. However, this article doesn't explain anything about why that would increase the likelihood of error. Please explain.

    Hi Charles,

    As a best practice, we recommend you to run the test for an integer number of weeks to ensure that the data collected by your test is not biased.

    We have added this information as a note in the article. In case you still face any issues, feel free to reach out to us at support@vwo.com.

    Thanks,
    Vaibhav.
