Do you have a source? Part of the reason for misinformation is that individuals / countries / brands / situations ( time ) vary alot. Which is why skilled providers are ( or at least *SHOULD* be ) the penultimate authority for information like this.

There is already a sticky for this, and one with greater numeric precision, as well as cited sources.
