this matches my experience as a dev manager. We had a bump in productivity initially, probably due to a fully-charged battery of team combined with less disruptions, but now productivity has declined by all our quantative measures (deploys, cycle times, failure frequency,etc). These are all proxies and not prefectly isolated, but better than "gut feel"
