 # Model Pulse data
 
-Daily download and like history for every actively used model on the Hugging Face Hub, from 2024-07-29 onward, updated every day. It powers [Model Pulse](https://huggingface.co/spaces/tardellirs/model-pulse), also at [modelpulse.ifsp.dev](https://modelpulse.ifsp.dev) with a page for every model.

 ## Notes
 
 - `dl30` is the Hub's rolling 30-day download count. `dl_all` (all-time downloads) only exists from 2025-02-27, so exact daily downloads, computed as the difference of `dl_all` between snapshots, start on that date.
 - Some days are missing in the source (Aug 2024, Jun 2025, Apr 2026, May–Jun 2026). Totals are unaffected; daily values across a gap are averages.
-- A model is tracked once it has 10+ downloads in 30 days, 50+ all-time downloads, or at least one like.
+- A model or dataset is tracked once it has 10+ downloads in 30 days, 50+ all-time downloads, or at least one like. A Space is tracked once it has a like; the Hub doesn't publish visits for Spaces.
+- On some days the Hub's download counters stand still and catch up a day or two later. `hub_series` spreads each such episode evenly over its days (sums unchanged), and the snapshots inside it are listed in `skip_days` (`meta.json` for models, `repos_meta.json` for datasets) so per-repo series can do the same.
+- `uses.parquet` comes from the cards as they are today, dated by when each Space or model was created, not by when it started using what it lists.
 - Download counts follow the Hub's [counting rules](https://huggingface.co/docs/hub/models-download-stats); the Hub occasionally books delayed downloads on a single day.
