Different outputs for one model

I would like to ask why Ventusky has different outputs from the Icon EU model in one place (compared to outputs from a competing application), unfortunately to the detriment of Ventusky's accuracy. It is not raining at the specific location, the competitor's model does not show precipitation, but Ventusky does for several hours. Longer update times? Where could the problem be? Thank you.

The ICON EU model is updated here every 3 hours, so we always use the freshest available run. However, that doesn’t necessarily mean it is more accurate at a given moment, so you can’t tell what is more up to date based on a single run, and another app may be using an older run.

Please note, that information about which run is being used is shown after clicking the “i” icon on the website, or in the app settings under the model overview.
