Have my setting in my recipe editor set to "fermenter" batch size. However I've been thinking about switching to "kettle" batch size. So here is the problem I come across. If I change batch from fermenter target volume to kettle target volume and adjust the kettle target volume to the essentially the same as the fermenter minus the losses listed in my equipment profile and under water requirements the og drops by 3 points. Both batch types end up at the same post boil volume so I'm guessing there is a bug one of the calculations.
