The important part of this process is the rest time after balling the dough. The longer you rest the dough the better. I find that by 50 mins dough is extensible enough to be flipped. However, if you can rest the dough longer, you will find that it becomes even more pliable but the improvement might only be 10 to 20%. If you leave your dough overnight, you allow fermentation to take place and your dough will have time to develop a full bodied flavour.
