I just activated beersmith 2 and am having issues with differences in attenuation calculations. For example, I have my avg attenuation for US05 set to 80% for a recipe with an OG of 1.052. In Beersmith 1 the FG estimate is 1.010 and in Beersmith 2 the is 1.008. I have made sure that mix/max attenuation figures work out 80% attenuation. Any ideas?
