This is an incredible challenge! I can't believe I solved it with not that many macros in my past. Very creative and a great use case of nested macros, at least in my solution.
I'm not sure about the story, but Mr. Kaprekar is very real and an extremely talented and underrated mathematician! His story is fascinating as well!
My lucky number is 2 which is the 2nd rarest (shared by only 576 other numbers) only losing to 1 (384). 3 and 7 are by far the most popular ones with 24% and 22%.
It's also interesting how 7 iterations is the maximum it takes to reach the magical 6147. I wonder if it has some relation to the Kevin Bacon 7 degrees of separation...
