I find it difficult to understand how %(% traffic allocation, % of target audience) works in experiments.
Let's say I need to implement the following experiments:
1. 50% of the audience in a certain segment is involved, 50% of this audience receive default data, and the rest of the received data override title data.
2. 75% of the audience in a certain segment is involved, 25% of this audience receive default data, and the rest of the received data override title data.
How setup these experiments?
Is this right?
1. 50% traffic allocation, 50% of target audience of controll variant, 50% of target audience of treatment variant with override title data - image1
2. 75% traffic allocation, 25% of target audience of controll variant, 75% of target audience of treatment variant with override title data - image2
And another question, only accounts that were created after the start of the experiment participate in it?
