Couple of comments: I’d suggest reading up on strokes gained. The 10 to 20 yards you discuss does provide an advantage and it isn’t about hitting fairways. Also The faster you swing they farther the ball goes and the farther it goes offline. A 1* open clubface will be farther offline at 300 yards than it is at 200 yards; that is how angles work.
While the strategy may not work every hole the percentages play out over time.
