- What does that do for compression?
- What does it do for the pesky charge hiding in the area enclosed by the piston, sleeve and top ring?
- What does the removal of 2 microns of play with a much smoother surface do to optimize the stock pressurized lubrication of the main etc bearings in an engine? (Yes the electron microscope? pictures do show a smoother surface if you bother to look)
- What happens when you remove 2 microns per link from a run in to somewhat worn cam chain?
- What happens if there is 1 micron less valve clearance?

1) Engine design involves STEM.
2) STEM includes 'Mathematics' at its trailing edge.
3) I presume that you've already calculated the differences that you reference and await mathematic confirmation.
4) Should that be the case, you'd already know the 'folly' of the whole enterprise, given the differences in volumetrics you speak of, and the 'presumption' that they would even exist at all, and lastly, your ability to even discern the effects.
5) Your arbitrary deference for 'smoothness' may be diminished when you realize that too much of it spells complete disaster for an engine.
