Hi,

Kageyama wrote that, in his experience, a player faces four barriers at: 12-13k, 8-9k, 4-5k, and 1-2k.

The ‘barrier’ levels seem to imprefectly relate to the Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13.

What do you all think? (an idle weekend thought :lol: ).

Cheers
tezza

I'm sure that you have a great future ahead of you in phrenology or alchemy.
Or maybe selling derivatives. :mrgreen:

I think that, on this topic, Kageyama was full of it. The only barriers are in your mind.

He got it wrong. Actually they're at 3d, 1k, 4k, 15k, and--rumor has it--at 92k.

Oh my gosh, tezza, you're right! Note how they also imperfectly fit into:
Natural numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
Primes: 2, 3, 5, 7, 11, 13
pi: 3.14159265358979...
sqrt(2): 1.414213562... (80% of the first 10 digits! Wow!)
e: 2.7182818284590452353602874713526...

Incredible & amazing! And what Joaz said. :mrgreen:

Wow, if someone's 92k, they must not even know how to put the stones on the board. <<

You know, it's funny, I had no idea what this was supposed to mean, because they have a sort of rhythm in my head, like a telephone number. One four one five nine is a single discrete chunk, and then two-six-five is the next... nine-two just doesn't compute!

The dan ranks are to the left of the decimal point

Same here, 14159 and 26583 are distinct chunks in my mind... It was kinda difficult to split them up, I had to check like a dozen times that I'd done it right. :)

Actually, I think the correct barriers are at:

4d, 3k, 5k, and 8k

hint:
19
hint 2:
4.358
