Feeding the barm, numbers vary
Peter Reinhart suggests doubling the barm whenever refreshing. So for 1 lb barm, he adds 8 oz of flour and 8 oz water. Is this the same as teh 1:1:1 ratio I'm seeing on here?
Also, he suggests refreshing after 3 days where here on the 101 tutorial, it's suggested to do so once a week.
