It would be interesting to know how many standard deviations is 775% extra demand from the norm. More than six standard deviations is rarer than a 1 in 506797346 event.

Samples getting 6 standard deviations away from the mean can happen 1/6² ≈ 2.7% of the time. You might be assuming properties of the distribution that aren't true.

Isn't that an upper bound? It says that it happens at most 2.7% of the time

Yea, it's an upper bound. The actual percentage depends on the distribution and can be anywhere from 0-2.7%. The Wikipedia link has more details.
