Please explain the meaning of the update time.
I have premium subscription.
Why the same model can show 4 hours and short time after 56 hours?
The methodology us not clear

I assume you are talking about the ECMWF model ?

See what is the meaning of update time.

Below is the schedule for this model (HRES is the high resolution model from ECMWF that you get in Windy).

You see that the forecast steps are more than an hour apart after 90 hours.
Dissemination is when raw forecast data is sent to users (Windy is one of these users)
Note that Windy requires then about an additional hour to process the data and produce the resulting update of the app at update time.
