There is a more current version of the PBSA Guide.  See DFARS PGI 232.1001, "Additional information and instruction on performance-based payments are provided in the DoD Performance-based Payments Guide on the DPC website in the Price, Cost and Finance section under the Performance Based Payments – Guidebook and Analysis Tool tab at https://www.acq.osd.mil/asda/dpc/pcf/pricing-topics.html#pdp"

Also, the A&S/DPC website above provides links to the PBP Guidebook, the current version of the PBP tool, and PBP webinar training that can help you understand how to use and analyze the PBP tool and structure.  Additionally, DAU has a PBP course (CLC 057) that may further help you.
