I'm having an issue with incorrect water volumes in BeerSmith 2.1. For example, I have a recipe where the brew sheet calls for a total water volume of 10.98 gallons. The mash calls for 37 quarts (ie. 9.25 gallons) for a water to grain ratio of 1.5, and a batch sparge volume of 4.05 gallons. By my calculations, that's a total water volume of 13.3 gallons. However, that seems a bit extreme. When I change the water to grain ratio, the sparge volume does not change. What's going wrong here? See attachment.
