I've been using the software and entering info which on my latest brew yesterday punched out an expected O.G of 1.050. During the brew I took samples pre-boil and post boil, cooled both overnight to pitching temp in the F.V fridge and measured today. Same temp, same hydrometer. Pre-boil came in at 1.050, Post boil came in at 1.060. Seems a such big difference, and now I'm not sure which to use for my O.G!? Does the boil produce/convert more sugars? Having never used these functions on the software before, or taken a pre-boil measurement I'm now confused. Also wondering if any trub or cloudiness in hyro samples would contribute to mismeasurements? While both of my samples were quite clear in this case, I've often thought it might give a higher reading if clouded. After punching all this in my brewhouse efficiency spat out at 78%.
