I am making a recipe using a (biab) partial mash, where I add 3 pounds of DME at the end of the boil.
Adding the extract at 0 minutes of the boil, BS2 does 2 things wrong:
1. it places the DME before the 0 minute hop addition
2. it changes the pre-boil gravity to look as if you added the DME pre-boil, which is just wrong.
As far as I understand, the DME should be added at the end of the boil and not after it has cooled. If I check the "add after boil" box BS2 moves the DME to the next box below the yeast. Adding the DME then would be dangerous since there could be bacteria hiding out in the DME.
Right now I am just trying the trial version, (windows 8.1) but it says it is up to date. Pretty annoying problem.
Additionally, any time there is an extract in the recipe the "Measured Efficiency" box goes up way past 100% (it says 111% for my recipe).
I've attached the recipe with which I have encountered these problems. You can see the pre-boil gravity says 1.091, but it should say 1.058.
EDIT: To clarify, I am adding the extract at the end of the boil to get greater hop utilization, since I currently only have a 5 gallon pot. After it cools, I add (previously boiled and cooled) water to bring the volume up to 5.5 gallons in the fermenter.
EDIT 2: To further clarify, if the "Add after boil" box is checked on the dry extract, the efficiencies are as follows:
Measured efficiency: 127.7%
Measured Mash Eff: 72.8%
And if the "Add after boil" box is unchecked, they are:
Measured efficiency: 87.2%
Measured Mash Eff: 32.3%
So you have to switch back and forth to find out both numbers.
OFF TOPIC:
I imagine there must not be many partial-mash brewers using BS2 if I am the first person to have this problem. I myself have been using Brewer's Friend up till now, which works just fine but I want something a bit more powerful. I plan on going AG in a couple months so this may not continue to be a problem, but one thing I miss is the Brewing Sessions that Brewer's Friend has, which allows you to take a snapshot of your recipe at brewing time and then track your progress and numbers throughout the brewing session.
It seems with BS2 this would not be possible, that you just have to change the "measured" numbers for each time you brew a recipe, so it is not good for record keeping.
I do prefer a good windows program over web software. In fact, we have been having bit of a blizzard here in MI and last night when I was making this recipe I lost internet, and was not able to plug in my numbers to BF, but still had use of BS2. Have you thought at all about adding some sort of Brewing Session type functionality? If you did and fixed the bugs BS2 would be perfect in my eyes. (The trub/chiller loss is very confusing. Do you mean hop absorption?)
I've done a bit of dabbling in C++ (the most beautiful/powerful language!) and would love to help with this software if you need it and use C++, just to get some experience working on something real. I am extremely busy for the next month and a half but after that perhaps. If not, no biggie, just fix your bugs.
