I am currently trying to find a solution on calculating a conversion rate w/out number of transactions for that unique person/device might complete. Originally I was using orders divided unique visitors but for this particular use case, about 30% of my customers are converting multiple times so it is throwing off my test results for the two experiences. In one case, someone converted 23 times (a greeting card experience) and it's made reporting test results more complex than it should be. Is there a way to do what I am after?
