Dear Matt,
The reason i have asked for the Product Variable on Read Review is to understand the actual impact of the review on the product.
Lets say I have landed your site and read a review for 'Camera' and then applied for 'Laptop' without reading Laptop Review.
Your segmentation will have the above behaviour counted into the bucket, but actually it is invalid.
If you have Product Variable Captured with Read Review, create a segment with Read Review exists 'Then' Orders exits (Within Visit, or the time period you define in Whithin seletion) and go to Product Report to add both the metrics for impact.
Thank You!
Arun
