Cool, I came up with 2.8 gallons as well.
I'm not sure how I over shot OG so drastically. This was my first parti-gyle and I'm pretty sure I over thought it - as I have a tendency to do.
It was 32 lbs of Pilsner, 5 lbs of rye and 3 lbs of dark candi. I hit my numbers for the 2nd beer, so I'm not sure where my math went wrong.
I think I'll boil just over 3 gallons and hop it like a regular boil, cool it and dilute the beer. I'd really like to end up with the Fred clone I was trying to make.
