 ## When did it stop?
 
-It is still ongoing. We will declare this experiment "concluded" once most of our Exit relays [have upgraded](https://metrics.torproject.org/versions.html) to Tor 0.4.7 or later, have upgraded the onionperf instances, and released Tor Browser Stable with Tor 0.4.7.
+There is no clear date when we transitioned away from the experiment phase.  At the time of writing this (06/09/2022 13:30 UTC) roughly 82% of exit relays (by consensus weight) have upgraded to Tor 0.4.7. Additionally, we have upgraded our onionperf instances and Tor Browser starting with 11.0.13 (released on 05/23/2022) is shipping with Tor 0.4.7 as well.
 
 ## What potential problems to look for, and how to report them?
