As of the second feeding, the storage starter is no longer turning runny in the slightest. Perfectly spongy, at least doubling itself, may be a little more than doubling.
Having read last night that I need to keep the amount of feeding proportionate with the amount of starter, lest new organisms take over, today I cut the feeding back. I dumped 1/2 the starter, leaving 1.5 to 2 cups. Then I fed it 1/2 cup water and 3/4 flour.
Don’t know if I mentioned it, but I live in a very dry climate, so I’ve learned to cover my starter with a wet towel instead just a dry cheese cloth or paper towel. The extra moisture from the wet towel seems to help keep the top of the starter from drying out. I started doing that pretty early on. If I forgot a feeding, there was a dry layer on top at the next feeding. But then I found that it was even drying out some on top before the proper 12-hour feeding.
Anyway, looks like the starter is in great shape. Whew!
