Ask HN: WFH vs. RTO Productivity Data?

At the moment, many companies are trying to enforce RTO to at least some extent. Personally, I found being in the office once a week is my sweet spot although it costs me almost 4 hours of commuting. Both sides, WFH and RTO seem to argue with improved productivity.

So my question: Is there any published data or research on WFH vs Remote productivity?
