Since my equipment calcs the pre boli and post boil water amounts, how does this equate the amounts of water in the Mash Guidelines section? Example: In my Robobrew profile I listed 1.5qts/lb for mash. With a 10.5lb grain build that would mean approx. 4 gallons of strike water and roughly 2.8 gallons of sparge water. But after the calculated losses in the equipment profile, my pre boil water will be around 5 gallons. What am I missing? Is this why I am missing my gravity numbers? I hope this isn't too confusing. I cannot get the correct water volume and I'm thinking its because I dont understand the calcs. Help!!!!!!!
