I plan on doing a hefeweizen this week and I'm going to do a mashout so that I can do my sparge in one step instead of doing a double batch sparge. I have reason to believe my mash pH is dropping too low when I get around to the second sparge. That, and my efficiency is pretty high right now, and I'd like to normalize it in the 75-80% range.

Anyway, my question is, in the spreadsheet, am I supposed to add the mashout volume to the "Mash Water Volume" section, and subtract it from the "Sparge Water Volume" section?
