Screenshots

The report now:

Description

Basically, the plugin is sending a usage report corresponding to the average usage on one year even though the user chose the daily option (therefore the report should show the last day usage).

On the second screenshot, you can see the CPU usage sent by the report (2.09%) is not matching the last day consumption of the CPU in the stats tab on XO (first screenshot).
The last screenshot, you can see that the new version of the plugin is sending an accurate value for the CPU usage.
