Structured Profit/Fee Objective FAR 15.404-4

Does anyone know where I can find the original study Defense Financial and Investment Review June 1985 or other relevant reading?   I assume it discusses how  the weighted guidelines for the DOD Structured Profit/Fee Objective risk  ranges (2-7% etc) were set?.    I am looking to see how this study could be leveraged by other smaller agencies to develop its own profit/fee objectives and ranges for assigning risk (why 2-7%? and not 2-15%?).   Many thanks for any help or any helpful reading on this (other than Nash and Cibinic Cost Reimbursement Contracting which I have of course read).
