[Plugin: A/B Test for WordPress] Can this work with a goal of Bounce Rate / Time on Site?

I like the theme split-testing, and can this work with a goal of Bounce Rate / Time on Site?

Or do I have to use whether they click links (and does this only measure to External sites, or Internal clicks too)?

Also, thanks for making this plugin! SES Theme Split Test seems to be too far outdated to risk using.
