I am getting ready to do this as my first AG. I've ordered the grains and build a mash tun, as well as purchased a copy of Beersmith 2. I plugged the recipe into Beersmith and got the numbers below. I am new to Beersmith, but the numbers don't match the OP with the recipe details, so I'm concerned this won't come come out right. My biggest concerns are the calculation of mash water, 2 step batch sparge (instead of 1), and the IBUs and OG appear to be off.
Any comments on what I'm doing wrong in Beersmith would be GREATLY appreciated in preparation for brew day (and in helping me to learn the software):
