Yes, you'd make 5g of a big beer and 10g of 1.050 beer.
Here was mine:
8.5g batch, using 2g/hr boiloff (since you'll have two boils at 1g/hr each...or whatever your boiloff rate is)
American 2-row 16lbs
American Crystal 40 1lbs
Estimated OG 1.052
First 1/3 yields just under 3g. 1.078 (made a IIPA)
Second 2/3 yields just over 5.5g 1.039 (made a Kolsch)
I collected 10.8g after the mash. 4g. went to the IIPA, 6.8 went to the Kolsch. After boiloff there was the ~3g and the ~5.5g.
What I did was to work backwards on volumes. I knew I needed 4+g and 6.5+g pre-boil. So I made 8.5 final volume with 2g/hr boiloff and saw that the preboil would be enough for both batches, 10.8g.
I know that's confusing, but I'm willing to explain the fuzzy parts.
