The short answer would be Admin > Metrics, basically put your community URL in front of this:
t5/bizapps/page/tab/community:admin:analytics-main:advanced-metrics?board_selection=<board.id>&date_range=3-7-2023%2C3-14-2023&granularity=Weekly&metrics=avg_thread_response_time&metrics_scope=board&user_selection=Empty
add a board ID (you can also choose categories) and that should give you the data you want for a single board or category.
There's of course a custom/long answer to this which involves coding your own solution, but maybe the above is all you need?
The "automatic"/easy way is basically the metric "avg_thread_response_time", but technically we can also calculate that by ourselves, it's just much more, let's say, "involved" 😉
When you run that report, does it email you a CSV chunk dumped in the body of an email? (that's what it sends me)
I wonder if there's a way to get it to email the CSV itself, or heck, display the report on the UI.
