I looked at your running rigging upload. I noticed that it states that the Genoa sheet 16 mm polyester 42 meters. And the Excel file that I uploaded states the Genoa sheet is 18mm, length 2 each of 21m Polyester red mark. The length is the same but the diameter is different.
I have tried both 16mm and 18mm. I really prefer the 18mm. I recently purchased 42 meters of 3/4" (18mm), STA-SET series from New England Rope. I really like it. It is not as stiff as the original and is not prone to kinks.
