Numbers Don't Add Up

While I like the visual, the numbers don't add up. The normal accumulated rainfall for the 8-Station Index (8SI) from Oct 2011 through January 2014 is 126.5 inches, and actual accumulated amount has been 92.0 inches. That's a deficit of 34.5 inches. Given http://www.cnrfc.noaa.gov/precipForecast.php?cwa=RSA... a conservative forecast precipitation amount for the 8SI would be about 5 inches or about 14% of the deficit. Given a 5-gallon bucket (640 ounces), 14% would be 90 ounces or 9 of the displayed 10-oz mugs.
