@idefix37 As a paraglider, you need to worry about every drop of rain; the amount of water that falls to the ground doesn't really matter. At my location 0.1 mm could mean a long period of light condensation (non-flyable) or a very short localised shower (high clouds warning), but if there is a decent chance of rain, your brain's danger control light should be blinking twice as fast. Therefore, a 3-hour forecast provides textile pilots more decisive information than a 1-hour forecast, which is premium and should be more detailed.

I understand that — it's a UI problem, not an algorithm problem — but the forecast feels entirely different. As a sailor, you don't care, but as a paraglider, I would go up the hill at 10, then swear and wonder why I'm paying extra for a 1-hour forecast that's no more accurate.

Have a look at a attached screenshots. Same model, same place, the only difference is that the 1h forecast switch is on:
