How to go from 4 oz starter to enough to bake bread tomorrow

How to go from 4 oz starter to enough to bake bread tomorrow

I’ve got a starter ready for breadmaking I believe.  For a week or more I fed 2oz starter with 1 oz water and 1 oz flour.  Last night I did not throw out any of the starter so I had 4 oz starter, and added 2 oz water 2 oz flour.  Today in volume I have 1 cup after I stirred it down.

I would like to bake the bread tomorrow.

Based on the information above, how much starter, water and flour should I use to build the starter volume up enough to use it and have some leftover?  I would feed it every 8 hours or so.

Thanks!

Ginny
