Hi everyone, here for a query. We want to do multiple experiments and instead of using strings,numbers or JSON , we use a nested ON/OFF to get it working but the traffic split seems to be skewed. Can someone help out ? Eg - To run test A,B,C ( 20%,20%,20% ) along with Prod Build ( 40% ) - We have setup 3 exp exp-a, exp-b and exp-c and logic goes like if ( exp-a ) { if ( exp-b ) { if ( exp-c ) { log ( exp-c); } else{ log ( exp-b ); } } else { log ( exp-a ); } } else { log ( “prod”); } }

what traffic splits did you choose for the different experiments? I don't think nesting like that will work very well.
I think it could theoretically work if you do a 60/40 split for A, a 66.7/33.3 split for B, and a 50/50 split for C. But you would have to do custom assignment logging and not use the built-in trackingCallback.

@future-teacher-7046 This is exactly how we have done. 60/40 for A, 66/34 for B and 50/50 for C but haven’t done custom assignment logging. Where can i read more on that?
@future-teacher-7046?
@fresh-football-47124 Can you help here?

I can try
I think jeremy means that you would have to check the user attributes and fire the tracking event yourself

Is there a document for this?

I'm not sure why you don't just use a numeric or string experiment
and just map those values to the sections of your experiment
would be a lot easier

We had a code running and it worked for us so expanded on it
But could this be because of Growthbook’s deterministic hashing that nested booleans don’t work as expected?

we can help you out in a few hours, if you want to meet - we can perhaps help you find a more scalable way

That helps. We are from India and we couldn’t find best slots in the next two days. If any ad-hoc support can be given in the next few hours it would be very verry helpful!
