The mix rate for star san is one ouce for five gallons according to the label. But I hear people mixing one tablespoon per one gallon. So if my math is right, 1 ounce = 2 tablespoons. So then one tablespoon would actually make 2.5 gallons. But if people are mixing at a higher concentration, would it still be "no-rinse"?
