It's not like it's magic, I guess, but all of my metal bench planes are fitted with it.
The washita that I used for durability testing (that posted a good number) is enamored with it as a finisher - it finishes more finely than carbon steel on that stone, and it continues to deliver a super bright finish.
I've been tardy on compiling the report document, but it's busy time of the year for me at work for at least the next month.
Never received a response from SB metals about whether or not they could provide me with ground .140 material, so I'll assume the answer to that is no. Which is a bit of a disappointment as I'd love to dump it in two of my infills.
