The instructions I follow for my pourover requires 350 grams of water. Much more than 8oz. It drives me crazy, but it also tastes good! Though If I only poured until reaching the 8oz mark it's also quite nice. That said, there is a question of "full-extraction".
Usually the ratio is 1:16 for full extraction without bitterness @200f with grain size slightly larger than refined sugar. That’s to maximize taste, without regard for nutrients. The bitter compounds probably make no difference.
