Determining Duct Leakage based solely on blower door and pressure pan testing

Can someone point me in the right direction to a spreadsheet, formula, or other related information that will show me to approximate/calculate total duct leakage based upon pressure pan tests during a blower door. I’ve been told by a few that it can be done but have not found the resources.  Any help would be greatly appreciated.See More
