Before you write in about a figure
Every calculator and guide cites its source at the bottom of the page, and the full bibliography is on Sources. If a number looks wrong, the fastest way to help us fix it is to include the page you're looking at and, if you have one, a more recent or authoritative source for the correct figure.
