OK, I have one other question.
When calcualting the Water Needed I seem to loose a lot of beer to Hot break in my Kettle, so i was running some calcualtions. Here is my question. When you increase the amount lost to trub, the calculator just keeps increasing the preboil amount. So, lets imagine my Preboil gravity for my recipe is 1.043 and this recipe calls for 14 pounds of grain (13 pilsner and 1 carapils). So if I now increase my Preboil amount by 2 gallons inorder to compensate for the trub, doesn't that mess up the recipe. I would need to add 3 gallons by more sparge or top up water. By doing this you would be dilluting your Starting Gravity preboil right.
So, if I have a 6 gallon recipe from a book, and I get 2 gallons of waste in my kettle, do I need to scale up to a 8 gallon recipe in Beersmith.
This may be very confusing, but take the water needed calculator on one of your recipes and put in 30 gallons of trub. It just tells you to collect 30 more gallons preboil, but still says that you should have an expected 1.043 preboil gravity. I would have thought the program would account for your trub and increase your preboil water and increase the sugars to account for the losses.
I must be missing something. I keep coming up short on beer or short on gravity
