Hi Dewey team,

Hope all is well! I downloaded Advan data during 2023–2024, and I'm now revisiting it to ensure replicability for a submission that uses Advan. I would also like to potentially add more recent years to my analysis.

I noticed that the monthly pattern no longer appears on your website—only the weekly pattern seems to be available now. Could you confirm if monthly data is still accessible?

Additionally, I understand that there have been numerous changes to the data collection process since 2023–2024. I don’t expect you to disclose any of the proprietary data generating process, but could you provide some general insight into how the most up‑to‑date dataset differs from the older version? I heard that the number of POIs have decreased, and some visitation patterns are inflated?

Thank you for your help!

Best,

Fangyao
