Book of Death: The King must die [prototype] Velocity, last 14 days: rising across 14 days, 0.00 to 0.05 (low 0.00, high 0.05).

Confidence 20%

Confidence is the share of Velocity’s four components that could be measured for this game, scaled down again when there is less than a fortnight to measure over. Here, ratings had a measurable acceleration on 2026-10-17. Topic views and comments did not. We also have itch.io chart positions for it, which is the fourth component. It was observed on 14 of the last 14 days. How this is computed.

Not enough of the ladder to compare.

Only ratings could be plotted, so there is no second counter to compare the timing against.

Each line is scaled to its own change across these 30 days, so counters that differ by orders of magnitude can be compared by shape. The vertical gap is what matters: a line higher on the left took its change earlier. The real counts are in the legend, and the day-by-day numbers are below.

A blank change is not a zero: the scoring pass refuses a window whose nearest observation is too stale to compare, rather than differencing two points that are not seven days apart.
