How to get responsiveness from Facebook Graph API?

Question

Is there a metric that I can pull from the Facebook Graph API that would tell me either/both Response Rate and/or Average Response Time from a page

Answer 1

Afaik there is only one way to get the reaction time:

• Use /page-id/feed?fields=id,from to get all posts with the info who created them
• Filter out the user posts with the "from" field
• Get the time between the user post and a page answer (if there is one) post by post
• Calculate the average response time based on the resulting times

I believe Fanpage Karma does it that way.
