The portion 15% seems to crop up suspiciously in optimization contexts... this was noted by Gell-Mann in The Quark and the Jaguar. It's roughly the portion of false warnings sounded by certain tropical birds to gain uncontested access to food. Gell-Mann speculates that it is close to 1/(2pi)...

I'm not statistically mature enough to say whether it's just coincidence. For one thing, oodles of natural phenomena in no way follow the normal distribution.
