I've noticed that now mash temperature affects the final gravity. This is fine and makes perfect sense as an additional calculation. HOWEVER, I find it a bit nonsensical that the attenuation changes regardless of whether the user has already specified "custom attenuation".
In most of my recipes I specified a custom attenuation because I know more or less what my mash schedule and sugar additions correspond to, in terms of attenuation. I find it ridiculous that now if I tell the calculator that my attenuation will be, say, 80%, from an OG of 1.050, the calculator will not say that FG is 1.010, but it will make a calculation on top of my already-specified 80%. So now I have to adjust my number to a nonsensical percentage (e.g., 78%) so that the calculator will predicts the desired 80%. Please don't do this. Do not assume that the calculator knows better than the brewer.
My point is simply that 75% should mean 75% and 80% should mean 80%. An additional feature that predicts attenuation is nice, but "custom" means "custom". Maybe add a button "Brewer's Friend predicted attenuation", so that the user can choose.
