Decay: No Title is Permanent

No matter how high the score of the news is, it is the gradual dropping of this score with a statistical formula as time passes and the news moving down in the feed.

Information gets old over time. A very important news item with a score of 90 should not still sit at the very top hours after it went on air. The decay function gradually pulls the scores between 10 and 99 downwards over time. Critical items (operates in the 10-100 range) start at the very top but decay at the same speed; their privilege is their starting point, not durability. The badge stays for 3 hours; but the score does not freeze, it decays from the first moment.

Example: A news item that was at the top with a score of 90 in the morning decaying and moving further down towards the evening hours.

The decay operation is calculated with an exponential formula in the form of e^(-rate×age). This mathematical approach ensures that news dampens naturally instead of disappearing suddenly from the feed. The dampening speed is the same for all items. The difference of critical items is that they start decaying from the highest peak point (100); so they can find a place in the upper ranks of the feed for a longer time.
