Hi again! Quick question: is there any way to stratify the random assignation using a variable different from the one used to randomise? Let’s say we want to randomise by

user_id

, but keeping the same proportion of users from each

country_id

in each of the variants. Is this something Growthbook allows out of the box? Otherwise, is there any easy way to implement this on top of current GrowthBook randomisation process? Thanks a lot! cc @little-cpu-3178

Our SDKs don't support that right now. We only hash together the randomization unit and experiment id to determine the variation. In theory, as you gather more data, the visitors in each country should be evenly split, but we don't have anything to specifically enforce that.
