It does seem that a simple curve fit of previous production has yielded the best predictor of future production.
Taking a slightly more optimistic view, I might point out the claim that 150 tonnes production loss occurred due to the additional boiler installation which means that 427+150 might be a better indication of production capability for the month.
With additional heat exchanges to be installed at the end of January it looks like it won't be until February that production will be better than breakeven.
