*For example, if the station reports negative (the counter that Cumulus uses decreases in value) rain, Cumulus will normally ignore that, but if for 6 consecutive readings the rain cumulative count stays below what it was before, Cumulus will normally accept the new count as a new starting point. | *For example, if the station reports negative (the counter that Cumulus uses decreases in value) rain, Cumulus will normally ignore that, but if for 6 consecutive readings the rain cumulative count stays below what it was before, Cumulus will normally accept the new count as a new starting point. | ||
*While Cumulus is running (not when catching up with stored past values from the station log), it will ignore large increases in rainfall.

Because many positive values are realistic | Because many positive values are realistic, Cumulus generally will accept those odd increases as a result of accidental knocking of a tipping bucket gauge, due to wind effects on the gauge, or even due to the station electronics generating a rogue reading. The sub-answers below explain how to correct such errors. | ||
