OK, I made my first brick yesterday. It wasn't all that bad. It tastes
good anyway!

The main issue was that it was soggy in the center. The other issue
was that it did not rise very much. I tried to follow Feldstein's
method...I imagine that one would have to have a very active starter
and a very good rise to get 2-3x volume increase upon 5-8 hours of
proofing.

I will try round 2 tomorrow or the next day and advise further.

Thanks everyone!
