For EPD Option 1 or MIR Option 1, it would seem you can just submit 20+ products with EPDs and not have to provide any material cost data whatsoever in the BPDO calculator, since the cost calculation apply only to Option 2 for all these credits. Can anyone confirm this - I can leave literally all material costs blank?

Or have reviewers been asking for the cost data as well? Let's assume the project is only submitting Option 1, no cost related calculation credits.
