I’m not arguing because I’m right. Any argument is on you.

Two crankshaft turns for one camshaft turn. So that means two piston strokes for one open/close of both valves. Valves move half as much as pistons.

You may be forgetting that valves open and close over a very short period of cam rotation.

Someone should do the math and calculate piston speed in the middle of a stroke vs valve speed at the middle of it's stroke (both at the same rpm).
