I see that the Mash Complete log entry now takes strike and full mash volumes, where previously it only took one or the other. (When did this change? I don't see any mention of it in the changelogs.) But I no longer understand how it's calculating efficiency, and the FAQ is absolutely no help. Previously it calculated based on first runnings or full mash, depending on what numbers you entered, but now it takes two volumes but only one gravity reading, so it's not clear what BF is doing with the numbers. In my most recent brew session (https://www.brewersfriend.com/homebrew/brewsession/303289, it's private) I have entered both strike and full mash volumes, and the final mash gravity, and BF tells me I have a conversion efficiency of 65%??? That's definitely not right. I exceeded my numbers with this batch, so I know conversion is well over 90%. If I remove the strike volume, BF tells me I have a conversion of 91%. Low, but believable. If I leave the strike volume in but remove the full volume, BF won't calculate an efficiency at all and tells me I need a log entry for it. This is a regression - it's apparently no longer possible to calculate conversion based solely on first runnings. Efficiency calculations have always been a sore spot with me in BF, but I could always rely on conversion efficiency at least. Now, I have no idea what BF is doing. Please help!
