Hi Ido, The level of confidence is calculated, not controllable, and
there is no default value. We will suggest you make the decision once
the confidence level reaches 95% or above. Generally speaking, the
longer period of your test will bring more traffic and have a higher
possibility of reaching a confidence level of 95% above. For more
information about confidence level, please refer to the link
