I use Brewers friend for my BM calculations and you can set up your own system on there, they do have the Grainfather on their system but you would just have to alter it slightly. The dead space is 2.5 l on the Guten as opposed to 3.5 l on the Grainfather average efficiency is 70% for GF found the Guten about the same. Download the GF user manual to give you some idea.
Take particular notice of GF's rule number 1 Mash water calcs, grain weight in kg x 2.7 + 2.5 dead space.
