Looks like the Endorsement Rate is now showing
2.23 / block on
https://explore.veriblock.org/network-statsIt could have been a bug, or perhaps it was a result of a lagging moving average calculation. I wasn't able to find any source code for their explorer at
https://github.com/VeriBlock so it's not clear how exactly they are calculating that endorsements figure they display.
The endorsement rate has further gone up to 8.37 / block as of current time.
What is bugging me is that the Longest recent block time was 1.7 min a few minutes ago and now when I reloaded the page it became 4.0 min.
I think there is a bug on this site.
