      Try:

      # Change from 1 above
      fragile_destination_concurrency_failed_cohort_limit = 5
      # New, more stable feedback controls from 2.5
      fragile_destination_concurrency_positive_feedback = 1/3
      fragile_destination_concurrency_negative_feedback = 1/8

      I think that will significantly reduce the rate at which delivery is
      unnecessarily throttled.
