I have been using BeerSmith 3 for quite some time and every once in a while I need to use the Adjust Gravity tool for a batch in progress. This is an extract recipe with steeping grains which I steeped at the range given in the recipe. Near the end of the boil, I check the gravity with my refractometer (calibrated OK) and find that it is lower than expected, let's say 10 points lower. I use the Adjust Gravity tool from the Tools drop down menu and enter the required information and it tells me I need to add 1.43 pounds of DME to get the gravity where I want it to be. I have learned from past experience that if I were to add that amount of DME my wort would be way over the target OG so I added 1 pound of DME. I stirred it in thoroughly and when I was sure it was mixed well I took another reading. The gravity was within 1 point of spec so it begs the question of what is wrong with this picture. This is not just a one-time fluke, this overage happens every time I use this tool. Am I doing something incorrectly or is there something wrong with the tool?
