We have a profile script that is using a random number to assign users to different experiences. The random number once assigned is persistent.
Example:
Experience A - Targeting = random number less than 10
Experience B - Targeting = random number greater than 10
When I check segment comparison in Analytics using A4T variable (Target Activity > Experience) I can see some slight visitor overlap (less than 1%) between the two experiences. How is it possible for a single visitor (ecid) to go into both experience when the definitions are mutually exclusive?
Can anyone think of a scenario where this could happen? I am wondering if it's something to do with clearing cookies ? And specifying Target cookies vs. Analytics?
