* The rainfall totals shown on the ''This period'', ''This month'', and ''This year'' screens within the '''View''' menu are generated by adding up the daily rainfall totals found in [[dayfile.txt]] for the selected period.

**If you have set a 'year to date' value and Cumulus is being re-started when the year specified beside that figure matches the current year, your year-to-date amount is also added into this year's total. This should normally only be relevant in your first rain season of operating Cumulus, but could be used if in any season you needed to add an extra amount because for some reason you had a gap in your recording period. | **If you have set a 'year to date' value and Cumulus is being re-started when the year specified beside that figure matches the current year, your year-to-date amount is also added into this year's total.
