@Steven-Gawne
It is not a large difference.
The reason can be explained : Windy displays only rain amounts of 0.1 mm and more. So if you have per hour 0.02 mm, 0.03 mm, 0.04 mm, these amounts will not be displayed in the 1h steps meteogram. But 0.02 + 0.03 + 0.06 = 0.11 mm. This value will be displayed in the 3h steps meteogram.
If you don’t confirm, please show a screenshot.
