In many industries, control charts are used to monitor production consistency. Two standard deviations is usually considered a warning limit. Three standard deviations is "out of control".
Has anyone analyzed the US oil/gasoline production or inventory control charts in the last 12 months?
If you look at EIA Gasoline
at a glance, I'd say the US gasoline production control chart (Regional Gasoline Stocks) is "out of control". Are there any readers that keep up with the data closely enough that can confirm this observation?
