Aw, come on. You're complaining about the notation? It's elementary statistics: I learned about sigma in public high school, decades ago. "Standard deviation" it's also called.

The publication standards are 3-sigma and 5-sigma, as I said. I spelled out their values (approximately) just because I realized that not everyone would know or remember what they meant. In all seriousness, I worried whether I was being too pedantic in explaining them.

Today, I am complaining about evrything. Your reply was the most informative on the subject.

Can we talk about global warming instead?
