And don't calculate averages like Github Copilot or you'll get NaNs and/or panics when the denominator is zero

  func averageRuntimeInSeconds(runs []Run) float64 {
      var totalTime int
      var failedRuns int
      for _, run := range runs {
          if run.Failed {
              failedRuns++
          } else {
              totalTime += run.Time
          }
      }
  
      averageRuntime := float64(totalTime) / float64(len(runs) - failedRuns) / 1000
      return averageRuntime
  }
