Transmission Fraction in SAM's Help for Bifacial PV Module

I'm simulating bifacial PV modules with special focus on getting bifacial GAIN from the rear side of the module. In the bifacial section, the definitions and formulas for the transmission fraction in SAM's help do not match with each other. The document attached along with suggests the corrections. Please review and share your valuable comments. 
Thanks for paying attention to the document.

Hi Hamza,
