Pretty good job filling it out, but one thing you have to look at closer is VAW.
You seem to be falling into the classic trap that "batch size" = VAW, when it could mean quite a few things. Do a quick forum search on "low integrity recipe" here, and you will have plenty of reading material.
Most notable thread is
this one, although it seems that some people get butthurt after reading it instead of absorbing one of the biggest problems that homebrewers have in communicating with each other effectively.
VAW = volume at flame out, AND chilled ... not in the heated state (which would be a greater volume due to heat expansion, or simply as we call it - VFO).
Drop a quick note to those HBT members to find out this volume and you're good to go.
My assessment:
Yooper's Oatmeal Stout -
Desired VIF = 20.82L (not VAW) ... which leaves original VAW 23.11L. In section G, you want to set "hop sock Y/N" to Y (this can be changed back later if you are not using one, but this will get your numbers to match). Set this VIF number to 20.82 in section B for now, we can scale to your desired volume later.
Section D, remove the 32 in "i'm designing my own recipe ... ", as this is overriding the original VAW calculation.
She has her IBU's at 31.6, and I'm getting 29.5 ... however all the grains are matching nicely. It's close, but still might be worth asking her what her VFO or VAW was, kettle efficiency (not brewhouse), etc ... so that you can be extra sure. But, I mean ... it's 1 IBU.
From here, you just enter your desired VIF, done. Change back the hopsock value if needed as well. All this does, is simply make you more beer to account for hop losses (or less if you can squeeze the hop sack to reclaim it).
Gold Winning IPA -
Brewer states "I had 70% efficiency". I have no idea what they are talking about, because overriding BIABacus default kettle efficiency to that, and using 17.65 desired VIF to match the grains brings us a VAW of 20.59L and 83IBU (which is way off the 65 IBU mark). This could be correct, as I don't know what formula they are using. In yooper's recipe, I happen to know it's tinseth from previous experience with her recipes. Plus, hers matches anyway .. giving evidence of it.
They could be stating 70% efficiency as brewhouse efficiency, so you will need to ask the brewer some questions.
SNPA clone - Wow, that original recipe is a huge mess ... I wouldn't even bother.
