Hi Mark

...Do you think the WD software just isnt matched to the gauge..??

There is no need to set anything on the WD software. It gets the Collector Type from what is defined in the RX user config settings.

Can I put a decimal place in the TX config for the rain gauge, and make it 2.2 or something like that (instead of 2.0 or 3.0)..??? Or do you think I should crack the locktite and start mechanically adjusting the stop screws in the gauge..???
Cheers for now...

Yes you can. Not in TX user config, but in RX user config settings.
Also don't forget to adjust Cumulus Rainfall multiplier according to this formula:

Multiplier = Collector Type / 0.2

For a 0.2mm collector (Davis default) multiplier should be 1.
Also keep in mind that Cumulus shows rain values rounded to one decimal place, however internally it uses more decimal places.
Just to illustrate: If we use an 0.25mm rain gauge (like mine), on first click, Cumulus shows 0.3mm, on second click, we get 0.5mm, on third click we get 0.8mm. The total is always correct.
This will also happen if you set a Collector Type of 0.22mm. On the first click Cumulus will show 0.2mm not 0.22mm, on second click 0.4mm, instead of 0.44mm, and so on... but as said the total rain value, is recorded on log files correctly.
