I think 1 gal to trub/chiller loss is a lot and then its adding another 2/5th of a gallon for cooling loss. I think you might want to play around with those numbers. also boil off rate, have you done a 1 hour boil off with water to see what your rate it?
fill with 5 gallons, or 3 which ever you want, boil at the same amount you would when brewing and then measure after cooled how much you have boiled off. then input that number into BS. I dont' like using a % because well 12% of 20 gallons is not the same as 12% of 10 gallons so that seems kind of flawed to my mind.
EDIT: I just checked and it has me at 1 gallon loss to trub/chiller as well and my fermentor loss is .45 gallons hrm.....
i'd like to see what others have in those two spots. I don't think I leave a gallon behind, but I might will whats left in my tubing and in the botton of the keggle....it still seems high though.
