Method

Sampling

About every ten minutes the collector requests five public Stripchat listing samples. It keeps entries tagged jp, combines the draws by username, and keeps the most recent entry for a duplicate. The listing is randomized and coverage is incomplete. A missed collection adds no sample. Times use JST (UTC+9).

Live Board and rankings

Viewers and newcomers come from the latest successful snapshot. Newcomers use Stripchat’s new flag. The board shows a last-sample label once that snapshot is more than 20 minutes old. Changes compare consecutive snapshots separated by 8–13 minutes, and require viewer counts in both. IN means a model was first seen in this comparison. Public status time is elapsed time since the reported status change.

Movers rank by absolute viewer change. Growth rankings use positive percentage change against the prior count and require a nonzero baseline. The Watch controls are preview placeholders.

Weekly and monthly rankings

The current weekly table covers the trailing 168 hours. Weekly snapshots cover seven JST dates ending on the date in the URL. Monthly tables use JST calendar months. Current tables run through the latest available data. We show Collecting data if tracking started after the window began, if a required date has no successful sample, or if no model has a recorded viewer count in the window.

Rank is based on the sum of viewer counts recorded at sample times, then peak viewers, days observed, and total sightings. A viewer may count in multiple samples. Days are distinct JST dates and sightings count snapshots containing the model. Missing viewer values are omitted from the sum and peak.

Model pages

A page appears when the same username has at least three snapshots and a viewer peak of at least 50 in the rolling seven-day window. Observed days count distinct JST dates. The heatmap shows sightings by weekday and hour, shaded by the share of successful snapshots that included the model. Typical hours are the top three covered hours by observed share, then by sightings and clock order.

Tonight forecast

Tonight runs from 20:00 to 03:00 JST. The forecast pools available samples from the previous 28 night windows, starting once two different nights have data. Each model’s score is the mean of its observed shares across covered night hours, with each covered hour weighted equally. The strongest hour is its highest observed share. The board’s peak hour has the highest mean count of observed Japan-tagged models. Listing visibility is an estimate and can vary with sample coverage.
