Robobrew v3.1 35L
You know I'm not really sure...i know the water amount effects the mash thickness...in my old cooler tun I always used 1.5/pound and always hit my numbers. I guess its a bit of trial and error to see especially with recirculation.
I have never considered this. My friend has a 35L Robobrew as well but he uses the equipment profile in Brewfather while I use Beersmith. Our strike & sparge volumes are always very different with the same recipes and batch sizes. Maybe this is why. That said I've been using the standard 1.7qt/lb in Beersmith and so far that seems to work pretty well.
