Thanks guys.
Peter - This one was 75% hydration, and the starter percentage was of the formula flour. I have tried this same approach with 80% hydration, but I think the oven spring and baking through of the crumb is better at the lower hydration.
In regards to the starter, it was fed three times over the course of two days before being used here. The temperature of the starter was kept at 65 degrees, and the feeding consisted of discarding nearly the entire mix before being fed.
