@ty-simpson Reporting on approvals is fairly limited, as you can only see data on the process as a whole (approvers, approval start date, approval completion date, current approval stage name) rather than by the details of each stage.
There are a few ideas already posted on this exact ask (see here), so I'd recommend that you comment or up-like this feature request. And I can happily bring this to the attention of Workfront Product again for additional visibility.
I imagine you would like to breakdown each stage of the approval process and see who is the current approver, what date the approval was sent over, what day a decision was made, etc., but if there are other data points you'd like to see, please let me know so that I can work on building a complete business case!
