I am looking to do an A/B test through an Email Program utilizing nine different variants. I have this setup, but want to ensure the test sample size is setup correctly. This will be a one time send, and I want ALL templates to get an equal share of the contacts. With my current understanding of how this should work, I want to set the "Test Sample Size" to 100%. I'm just looking for validation that this is the correct way to set this up.
