The BAB was a great success! We managed to brew ~20 gallons of beer and that wort is happily fermenting away. We brewed a pale, yellow, fizzy beer with high wetness factor that should go well with heat, humidity, and bbq. We split the 20 gallons 4 ways with Peed taking 10 gallons and Daniel taking the other 10 gallons.

Some stats on the system. Measuring volumes was very spotty but I calculated that we hit a mash efficiency of 85%. My preboil volume and gravity were both above calculated values. The boil was quite anemic so I didn’t boil off nearly as much volume as I expected. This put us at 1.041 SG (v. 1.040 calculated). We left nearly 2 gallons of wort in the kettle as far as I could tell. If I had to do it again I would pump out of the kettle, not use gravity.
