Those results are truly amazing!

The striations in the second picture are remarkable smoother and finer.

I suppose comparing the first picture to the second would be similar to comparing a razor honing (on a stone) with more pressure vs. virtually no pressure. The paper as a cushion eleviated some of that pressure....truly amazing, since it's only a single piece of paper!! Just goes to show how sensitive the metal can be to the slightest changes.

Thanks for sharing!
