Problem with calculation when using custom fermentable

[Serge Marx]

It occurs to me that you'd only ever calculate a 100% efficiency on adjuncts, or DME / LME. It's never an option for grain - so why not have a separate option for custom DME etc, which is always calculated at 100%, then a custom grains options which is calculated based on your recipe (ie the default 35% for steeping, or the full expected efficiency as it's entered for full mash?)

regardless, ticking the box now sorts things out, and I've added all my custom malts, so as far as campers go, I'm a happy one.
