A ten hour wait doesn't really strike me as a pancake? You should have a "it's 730am, there's four screaming girls, only two of which are related to me, the dogs are begging for scraps, and the demand for pancakes has crossed into Veblen goods territory."
The default has the 'tang' slider at maximally tangy, which is where the yeast and wait come in. If you back off on that the recipe looks more like the standard quickbread I'm used to.
The yeast and ferment is going to make it more acidic, and more tender because the gluten will be weakened. I imagine you could use cake flour instead and get close to the same tenderness, but the flavor would be different.
It depends. The inspiration sometimes comes after a Saturday evening with friends and lots of drinks. Having a foolproof recipe comes in handy, and having the perfect stress-free pancake batter already made the next morning turns you into a household hero.
Man, at the rate I can generate pancakes I fear four children would murder me and just drink the batter raw. Though maybe I'd buy a second pan in advance xD
