Didn't check the link. Guess I was wrong!
That's pretty nearly the exact method of another well known maker who has written extensively.
You'll notice he cuts up 600 feet of hemp rope a year. He makes one knife a month. So, in the testing process for each knife, he must cut 50 feet of rope. If separated into three strands as explained, cutting 1/8" more off each time, you could get 288 cuts per foot of rope, or 14,400 cuts for 50 ft. of rope. Gee, that's a lot. Perhaps I've been to strict with my math, let's relax the standards to allow a few more knives per year, maybe some didn't get finished too, maybe some rope got wasted. Let's cut that figure in HALF. 7,200 cuts per knife. Now that sounds realistic.
7,200 cuts at one cut per second would take 120 hours. That's two 60 hour weeks of cutting. With the at least nine or ten days to do the rest of the work, I hope he's getting paid at least $2200 ($10/hr.) for that one knife. And I hope he has a machine to do all that cutting; sounds like a recipe for carpal tunnel to me... 1,440 hours per year of sitting at the bench, cutting.
That said, many makers such as Bill Burke, Ed Caffrey, Brian Tomberlin, as well as the author of the above (who I do owe some knowledge to) use triple quench and triple draw, among other techniques to get the most out of 52100. I use a fair amount of this steel myself, and triple quench/triple full draw, then soft-back draw it. (For sporting/utility knives.)
When I use W2, I'm almost always going for a hamon, so it's triple normalized then single quenched, then double draw. So, a fair bit more simple for me.
