A/B Subject line testing Percentage Clarification

I am doing my first A/B testing. I want to do a 10/10/80 with 2 different subject lines, but the "Test Sample Size" slider is confusing. There is a section for Recieves Test and Recieves winner. When the ruler is set to 20% recieves test and 80% recieves winner, does that mean that those that recieve the test will be divided into two sections of 10% each??

Hi Matt, 

Yes this is correct.  When you set the test percentage to 20% this will be divided between the test emails, so 10% each, with the other 80% receiving the winner.
