If you use our recipe in cronometer, you will see it says there is 1.7 carbs per serving. That's because there is no way to tell cronometer to take out the carbs that removed by the whey in the yogurt making stage. This recipe utilizes 4 servings of our yogurt recipe, which shows up as 15 total carbs. When you subtract the amount of whey removed, it comes out to 5 total carbs for 4 servings. (2.5 carbs per serving). If you remove the 10 total carbs from this recipe and divide by 15 (total number of servings) you get 1.1 carbs per serving.
