I apologize for the obvious rediculous of this question at the start.  I have starter in a jar and I make 1 loaf of sourdough at a time.  I use 1 cup of starter, 17 7/8 oz. of flour a little salt and a little olive oil.  I want to make like 8 loafs at a time and my question is:  Do I just multiply eveything by 8 or is there a subtle less need for starter or something?  Again I apologize but I don't want to mess up a bunch of stuff and waste food because I didn't check.

Thank you, Scott
