Nines When it comes to purity, you want as many nines as possible. With women, you want to date some nines when you are younger but ultimately settle for an eight - less maintenance and craziness. Just kidding ladies you are all beautiful.
3N+ is looking pretty solid in terms of showing signs of scaling and repeatability. 4N+ is clearly doable, as was achieved early on in test #19. But make no mistake, HPQ and PYR are on a mission to get 5N+. And these guys will obsess over hitting it until it happens. Whether it's next press release or in a year from now, one morning we will look on our cell phones and there will be a press release with 5N+ in the title. Until then, I suppose I can settle for a company commercially producing 3N+ worth only a couple of billion dollars instead of several billion.
