      Description

      Currently we use a simple average when calculating the total throughput/latency of backupo instances to compare it with the master ones.

      This may lead to problems of false positive View Changes when there is a spike on just one of a backups.

      Acceptance criteria

      • Define a better way to calculate the average for backups. Consider median which is more robust to spikes.
      • Write unit tests checking, in particular, that spikes should not trigger false positives.
      • Implement the changes
