It seems it is consistent, so it is one or other of the gauges calibration, either the gauge itself or the TX software. A few things, Are you sure the Davis is metric and have you altered the TX software to reflect its calibration. ie 0.2 for a metric Davis Gauge or 0.254 for an imperial one. (not necessarily the Davis that is wrong, might be the Oregon over reading.)
TX config file as follows;

*/
#define COLLECTOR_TYPE 0.200 // Please note: Values must be in metric units. Max. resolution: 3 decimal digits
// -------------------------------

Hi,
I have a new Davis rain gauge connected to my WD.
It looks like i'm missing some rain tips comparing to my Oregon rain gauge and to my manual rain reading.

In blue the WeatherDuino measured rain and in red the Oregon rain measurement.
What should i check to solve that ?
