Stop Cumulus first. Edit the original file using an editor that treats all fields as text [either any text editor, or a spreadsheet program that can be instructed ''not'' to recognise special field (like date) types].  Do not add nor remove parameters, simply amend the values and timestamps.  Note that figures are held internally in Cumulus in binary, and converted to Base 10 numbers for the value shown.  Since fractional binary values cannot be converted exactly to base 10 decimals, real numbers appear to be given to a strange decimal resolution with multiple decimal places.  Also note that the timestamp includes a calendar date, so for a 9 or 10am rollover, if you need to manually look for highs and lows for times between midnight and rollover, these would be derived from the daily log (dayfile.txt) row for the meteorological date (the date before the calendar date for those early hours).

The format of monthlyalltime.ini is similar to alltime.ini but the sections are repeated for each month of the year, distinguished by a two-digit number at the end of the section name, representing the month for that section. For example, the rainfall records for September are held in section [Rain09].
