Run an experiment targeting 100% users analytics show only 80%

Is it normal that if i am targeting 100% of users for an split test and then for the page /stop/

Then if i check in analytics the number of users who went to this page and compared with the number of users in the experiment is different?

 

For example analytics by creating a custom segment of people part of the experiment shows that 2000 people visit the page /stop/ and took part in the experiment.
Meanwhile all users visiting the page /stop/ were 2500 people.


This means that even if i set target to 100% still 800 people were not being targeted.


Why?

Thanks

There may be different reasons for the inconsistency.

 

For example the time periods may not match exactly; Optimize starts using data a little bit later from the time that your experiment becomes visible. See also

Furthermore, if you use the page hiding snippet, it maybe that some of your visitors or very slow networks "timeout" and are excluded. See:

i see much less, i targeted 100% and see about 20-20% of the audience flagged by a test. ive tried 50/50. 33/33/33 and now trying 98/1/1 to see if i can get any accurate count of visitors to each variant and the control.
