Hi there,

I've had some excellent help from this mailing list, and have
determined to repay the favor in my fashion – I had a very confusing
time calculating percentages for flour, starter and water, and so
wrote a small program to do it for me, and made it available online.
You can try it out at this page:

Let me know if anything seems wrong, or there's anything I can do to
improve it. Happy baking!

Yours,
Eric
