I'm still having issues trying to get eff/bh numbers to line up... I notice when I toggle the "target" from kettle to fermenter nothing changes except the wording next to Efficiency. I'm assuming that efficiency number is BH eff because it's either "ending kettle" or "fermenter" and not "mash effeciency". Or is the software assuming some value for conversion? I'm noticing that if I put "6.5" to the fermenter with 85% eff in the recipe editor and toggle "fermenter" to "kettle' that no values change... this seems odd to me if i have 4qt of dead space in my kettle. Having 6.5 in the fermenter with 4qt of dead space in kettle puts me at 7.5g in the kettle and my OG and IBU would be differetn than 6.5g in the kettle if nothing else changed. If i go into the equipment editor and make it say i have 5 gallons of dead space nothing seems to change. I would assume that putting exaggerated numbers would help expose the what's being used vs not being used. For now, it appears toggling the equipment doesn't do anything. I have to put my pre-boil volume in manually, i have to toggle my post boil volume to be "kettle" before I transfer to fermenter or else the kettle losses won't be present. It may help if i could understand the volumes used to calc the OG/IBU so I can set these values correct regardless of what "batch size" says.
