Warren the pursuit of perfection is a journey without end;
The closer you get, the more you focus and the imperfections are still seen, they just keep getting smaller and you keep magnifying, it is only when you step back you can see how far you have traveled.

Is a supersurfacer going to give you a perfect finish at all magnifications, no.

Keep in mind that technically the best surface is made by the first cut, as your blade edge degrades with each pass. If you were truly searching for perfection you would hone your blade for the final pass. But from a practical level a supersurfacer does an incredible job, at incredible rate, for a lot fo lineal feet between sharpenings.

Also i would caution you on making judgement of the surface from the video, as it is really hard to definitively say what the surface is like from the video. To be sure you would need to examine it in person, preferable under magnification. The surfaces have been studied and verified scientifically in Germany and Japan under scanning electron microscopes.

See images below.

What a supersufacer is, is an attempt at perfection; and at that it is the closest that i have seen.

They have put effort and research into understanding and improving the mechanics of cutting wood.

they have advanced and documented the specification of tool geometry.
They have researched and developed knife steel, grinding and sharpening.
A fine planed surface is a subtle but brilliantly beautiful thing to experience, but sadly something only a few appreciate or even notice.

They deserve a lot of respect for "going against the grain" When sanding is so much easier to sell.

Some woods that i dressed as sample, note the reflection on the walnut.
