How fast this chart renews itself

Over the last 7 days, the ranking in Kenya replaced an average of 28% of its entries every day, moving between 20% and 40% depending on the day. That is an unusually stable chart, where a hit installs itself for weeks instead of days. This figure comes from comparing our own daily snapshots: YouTube publishes the ranking of the moment, never how much of it survived since yesterday.

The chart carries about 50 entries a day, filled by 50 distinct channels, so almost every slot belongs to a different publisher. Concentration only appears when one channel places several videos at once, which is exactly what the ranking above lets you check.

The most resistant video of the week held on for 30 consecutive days: Mejja - Mboka [Official Video]. Survival time is a far better measure of a video's strength than the position it opened at, because it is the only one a launch budget cannot buy.

The sharpest climb belonged to 1000 Players Simulate Mining Prison in Minecraft, up 27 places in a single day. A jump of that size in twenty-four hours almost always signals an audience arriving from outside YouTube rather than gradual discovery.
