OBI - Offer time in approver queue

Although we use a DAR for the offer approval path, users are allowed to add additional approvers into the approval path. Because of this, the Recruiter is not always in the same number spot for every offer.

Has anyone been able to create a report in OBI, using formulas, that calculate time to approve based on approver names? Or has anyone been able to calculate time to approve in another way?

Thank you in advance!
