Not real piston rings but whats interesting here is you can see the blowby in the circumferential movement in the oil between each ring.
Faster between the top and middle ring than between the middle and lower ring.
So I wen and looked for research.

The paper shows it's important to have the ring gaps 180 degrees from each other too.
How long and if they will stay that way I don't know.
Assuming a 0.5 micron thick layer on metal surfaces, you lose 2 microns (0.002 mm) of space between piston and sleeve,
And 0.007mm off the ring gap of the 75mm bore of the engine used above.
I don't think that would make much difference to blowby, but don't know enough on the subject to judge..?
Interesting non the less.
