    My false bottom elevates the mash about 2 gallons worth. The 2 gallons will drain, so I'm not using dead space in the tradition sense. However, the 2 gallons does adjust mash thickness. For example if I have 24 qt of water with 12# of grain, my mash thickness isn't 2 qt/#, rather it's 1.33 qt/#. For those that have a similar false bottom, do you adjust for the dead space, in other words for my example, are you using 2 or 1.33?

    If you're having a dough-in problem, I suppose I'd decide what thickness I'd ideally want, then bump the water to grist ratio up accordingly (adding those additional 2 gallons).

    In your example, if I'd be happy with 1.33 qt/lb of "effective-dough-in-viscosity" (EDIV, new brewing term) , I'd enter 2 qt/lb in software to get there.

    ETA: I don't have this issue. I'm thinking out loud.

    Are you a dummkopf? Everyone knows all the terms concerning the mash tun must be in German:

    Everything I have read suggests that there is not a big difference between 1 qt/lb and 2 qt/lb, I would guess you are worrying about nothing. Not willing to play with Brew Cipher, but it seems like a calculator would give you an idea if this mattered.
