We're stuck in the Great OG and Efficiency war of 2019 and I'm not quite sure how the battle is going. Personally I've stopped using the equipment profile losses as they affect OG when they should just be changing efficiency. I just add it in the batch size. And use kettle as the target.

There's been attempts to fix this but it's caused more problems than it solved, so I think we reverted back to the old approach.

I've always used kettle then adjusted my losses from the kettle to the fermenter by hand and all recipes are spot on that way

I use fermentor volume and don't sweat the little differences. It generally comes out close enough for me and if not, I can adjust.
