Very interesting- It shows the cap iron folds back the chip in a way that applies tension to reduce tear out under the test conditions. The .1mm shaving is about 4 thousandths, which is reasonable, but when they set the cap iron back .3 mm from the edge, that is less than 1/64th of an inch (.75 of a 64th), and that does not seem very realistic. If there is any camber on the blade, you’ll just be using the very center of the blade. If the corners are taken off, you’ll need to worry about the cap iron digging in.
It’s a fascinating video to see how the fibers part, but I’m not sure how to apply it and also wonder what would happen if the mouth of the plane were included.
Thanks for posting this!
