Hi, I think there's a bug when selecting the fermenter as the target volume, and then looking at the quick water requirements. It does not appear to be taking into account the grain absorption into the overall total (this is an extract & specialty grains recipe), or 'water into kettle' volumes. I would expect 'boil water added to kettle' to be 12.2 to account for the 0.5L of grain absorption from steeping, leaving behind 11.7L prior to extract/sugar additions. If I set target to kettle, and set the target to account for dead space, the calculations appear to be done correctly. IMHO, for an extract recipe, the 'boil water added to kettle' should be top of the list, then the loss to grain, then the volume increase from extract, and then the starting boiling volume. Everything after that in the list looks right.
