One more initial q, the brewsheet says not to run off more than 6.25... why? I need to boil 8 gallons to get me 5 gal over 90 min with my kettle. I guess I just have to adjust the grist w/beersmith? I thought it was ok to sparge to my starting boil volume, even if it is 8 gal. I mean 6.25 gal boil over 90 min would yield much less than 5 gal finish with even a moderate evap and trub loss. So, I'm a bit confused there..
