"I think Beersmith seems to "lock" you in at 1.25 qt./lb. I wish you could enter in your own ratio and then it would calculate. I usually do 1.33 or 1.50 qt/lb."
BeerSmith does not 'lock' you into anything. You should edit your equipment and mash profiles to reflect your brewing process. Take careful measurements of your volumes and gravity readings through your next brew session and calculate the grain absorption, trub losses, and boil off rate. Use these figures to rework your equipment and mash profile. Repeat until the program can better simulate your actual figures.
