Valve timing has aboslutely nothing to do with compression ratio. Small amounts of overlap exist for a reason; they increase cylender flow rates by allowing the intake ports to remain open longer. Thus, the incoming intake charge helps expell exhaust gasses.
Where do you learn these things? I suggest reading a book on basic automotive engineering, or taking a class before you go any further. I'm not trying to be a jerk, but seriously... Go take a class at your local CC, or UTI, or something, anything. You know the basic terminology, but your understanding is fundamentally flawed. I really am starting to think you might just be the biggest, most epic troll and you're just pranking everyone.
