Honestly, this reminds me of how trying too hard often makes things worse. You see it everywhere, like overwatering a plant or hovering over a slow computer. With bread, I've found that once the dough feels smooth, you just have to trust it and walk away. More fussing usually just makes a tough, sad brick.
Yeah, I used to knead the heck out of my dough thinking more was better. One time I just stopped early on a whim and it was the lightest loaf I ever made. Makes you wonder, right?
