A short feed is the product
The radar is designed to say less. Routine weather, ordinary games and generic awareness days should not crowd out a major national match, an unusual weather threshold, a nearby natural event or a rare sky peak.
Location changes the answer
A local natural event may matter only within a few hundred kilometres. Public holidays and national-team fixtures can matter across an entire country. The scoring model treats those scopes differently.
Freshness is visible
Every live card keeps source context. If a feed is unavailable, the site reports that limitation rather than inventing a replacement event.
