10k Stars. Formula for extra shuriken/arrows?

[RadioactivePiranha]

I was wondering if anyone new exactly how 10k stars works. I know you can shoot extra arrows (with zen archery) based on your wisdom, but does anyone know what the chance for an extra arrow is?

If you are looking for a definitive formula, I think you are out of luck. But there has been a fair amount of testing done in the past which can be found in the following thread
