Sucess with prescriptive method and weighted average Tvis?

There have been a few post here about using a weighted average Tvis for the prescriptive method in the case where the design has two or more Tvis values in the same plane. Is there anyone here who has submitted on the credit this way? Did the reviewers accept it? Thanks

I submitted under older version of LEED. You can also refer to CIR dated 4/10/2007 ID# 1727. Although it is for older version, in my opinion, it 's still valid. Even on fritted glass or BIPV glass, the manufacturer only has one number although the glass has two parts (clear and fritted/PVpart) that have different visible transmittance.
