Started a fresh batch with some of the feedback I got. This is roughly 10 hours after the first feeding. This is similar to the result I got on previous attempts, except that it nearly wouldn't rise at all on subsequent feedings.

The recipe called for the second feeding to be 24 hours after the first, and then every 12 hours thereafter.

I'm going to try at the 12 hour mark though, since I think the problem was that it had starved by the 24h mark. I'm also using bread flour this time instead of all purpose. I started with whole wheat, because it's what I had on hand, and my wife might murder me if I tell her I need to get yet another variety of flour. ?

Is this common for a first feeding? My apartment tends to be quite warm, FWIW.
