Brian,
It appears to me that you store the monthly rainfall chart data in the ini file under [rainfall chart] one entry per month. all past entries appear to be correct except for july 2003. The last auto update was for 1.05 inches which we got in the first few days of the month. It never updated as we got more rain durring the month. I simply assumed that you updated it daily - maybe that’s wrong.
I just checked it now and it shows an entry for Aug 2003 of 27, which in the chart comes out to about 0.1 inches. Unfortunately today is 1 Aug and it didn’t rain overnight, nor was there a heavy dew.
I had been manually updating the entries after each rain so I could make best use of the chart. As a result I cant tell now if you made am end of month entry for July.
