  • the fryer vat is filled with new cooking medium on day eight (8), so the quality measurement drops back down to the new cooking medium level.
  • the used cooking medium is not replaced through day twenty (20), so the quality measurement continues to increase.
  • the plot depicts considerable short-term variation about the long- term trend.
  • the plot also depicts isolated measurements of much lower magnitude than the trend. This signal variability means that simply comparing the signal to a threshold at any given time does not result in a reliable indication that the cooking medium has exceeded the threshold with acceptable certainty.
  • the certainty of the threshold detection may be increased so that it can be used effectively.
