We have recently started using Sitecore A/B Testing and I am getting lots of questions about how the scoring works. I have been through the relevant Sitecore DMS documents but I still am not 100% sure if I understand how the scoring works.
My basic understanding is that the scores are based on Value Per Visit and my assumption is that the the value relates to the whole visit and not just the specific components we may be trying to optimize with the A/B Test.
For example, if option A has a goal associated with it worth 5 points, anyone presented with this option would get 5 points PLUS any other goal values they trigger during that visit to the site. That might add 5, 10, 50 or more to the visit score and then the option A score would be "total visits score/total visits".
Can anyone confirm if my assumptions are correct or explain where I may be off base? Can a user presented with option B change the score for option A?
