Do you have any links to sources around these other ways to get the data? I recently started working in this domain and trying to get up to speed on state of the art regardings these types of things specifically since im in the data team.
No. I once knew someone who did this for a big company back before the internet took off, but we lost touch. It is basic applied statistics, but likely there is a lot more than I don't know anything about. Likely you can ask someone who has done more study in that area to get details.
