Not sure, but I think it is also omitting the salts for the sparge water.
Is there a that gives the total amount of each salt for each addition? And is there an option for those that don't brew low o2?
ETA - I like the adjustment for boil off, but shouldn't the reduction come from the sparge over the mash?
PETA - fermenter loss is not consistent with other volumes. Everything is gallons but that.
I'm in defect hunting mode with work right now.
