What are the three volume measurements calibrated to in BeerSmith? There is the mash in volume (which for me is my total volume because I BIAB with no sparge), pre-boil and post-boil. My sight gauge is calibrated at room temp. Are the estimated values on BeerSmith calibrated at each temp...room temp for starting volume, mash temp for pre-boil and close to boil for post-boil? Or are they all set to one temp and we need to adjust our measurements?
