A4T - Profile Scripts

[#1]

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?

Hi Nicholas, is this random number generated just once or every time a visitor visits? If its latter AND if your activity is an XT then a single visitor may see both experiences depending upon the value of random number generated. Would be interested to get more details

Hi - the random number is persistent for the hist. lifetime of the profile (90 days). 

Any thoughts?

Cheers
