Why would you compare y1 D1 to y1 D2? That’s like comparing a 3 year old car to a brand new one. Wouldn’t you be annoyed/frustrated if you traded in your old car expecting to get a better one with the brand new one and it’s the exact opposite?.... F that. You’d Bring the new one back and demanded your old car back. D2 should have STARTED our bigger and better than D1. Not “slightly” better than y1 D1.
