Where does cumulus source yr rainfall

I've noticed that my rainfall totals are screwed up every time it rains.
The uploads to my website show the total rainfall for the year as 622.0, but everywhere I seem to look on the database shows 609.6mm.
This has the effect of showing a high rainfall of 12.4mm of rain per hour the next time it rains.
How can I set the rainfall to the correct value?
Here's my upload source that I refer to.

<tr class="td_rainfall_data">
<td>Rainfall This Month</td>
<td>0.0 mm</td>
<td>Rainfall This Year</td>
<td>622.0 mm</td>

On startup it adds up all the values in the dayfile - plus any correction you may have in the YTD Rainfall in settings, plus any additional rainfall logged so far today.

According to my rainfall this month I have now had 12.4mm . This figure was popping up through August too.
It seems my mistake was adjusting the total rainfall on my Davis Console back in August. On my set up the total yr rainfall on my console governs what Cumulus shows.
I have tried everything to try and eliminate the errors and I can only think that a complete reinstall is the only answer. My Console may be the problem -It's a 2006 console and weatherlink, wheras the rest of the system is around 3yrs.

Once Cumulus is running it uses the total rainfall for the year from the console to track the increments in rainfall.
So if you adjust the console figure that will affect MX. If you decrease the console value, then MX will recognise that as a correction and adjust itself accordingly. But if you increase the console value, then unless you also correct the data files, then that increase will be counted as rainfall. If you increase the console value just to get the console correct then you could probably add the same (but negative) adjustment into the Cumulus rainfall YTD adjustment value.

Continuing issues with rainfall errors. This is a p age from my rainfall uploads - its clear that there is a compounding rainfall error. Each day I get an additional 12.4mm of rain added to the monthly total. This is so infuriating! How do I eliminate this error? The more I edit the more errors I seem to get! The only true total was on the 2 Sept with 22.6mm. My total rain for September should be 23.6mm
