For a better crumb yet I combine the dough's flour and water (68% hydration - that is 500 gr flour and 340 gr water) without yeast and let it sit for the same duration as the polish for a "good" autolyse. (Good hydration is the key factor here.) The day after, before the kneading process I add the yeast moistened with about 20 gr of warm water and the poolish. Total hydration is apporx 76% (pretty wet) which yields a wonderful chewy crumb and crackling crust.
Baker's formula (in grams) is then:
Flour Water Yeast
Poolish:
100 100 7
Dough
500 340
Yeast
20 3
-----------------------
600 460 = 76% Hydration
