Is there a way to cap the users participating in a Split experiment?

 Question

Is there a way to limit the amount of users participating in the experiment?

 Answer

Within the Split Definition, there is no "cap" feature, however, its possible to limit the number of user in approximate way using the "Traffic Allocation" percentage.

For example, if the total unique users in the site or page used in the experiment are 1 million, then its possible to set the Traffic Allocation percentage to 15%, which will allow only 150k of the unique users into the experiment.
