Hello, I have a question about the interaction between a percentage based rollout and the additional targeting rules you can attach to it. Say I set a rollout to 50% of user and then also add a rule that $attribute needs to be A. How will this be evaluated? • Will GrowthBook first split the users 50/50 and then check the attribute to exclude people • Will GrowthBook first check the attribute and split only the users matching 50/50 I assume it does the second option but the docs do not mention this interaction specifically so I’m not quiet sure.

The order of evaluation shouldn't matter because the 50/50 split is based on the result of a hash of the user id with an experiment specific salt - thus a user is always either in control or treatment regardless of any other attributes being filtered on. For large enough sets of users this will hold valid, but in case the filter causes a bias in the split it means that there's some correlation between the filter and user id distribution.
