So sorry to do this Shahzad - @dominiqueclarke pointed out to me that the "total step duration" does not equal the sum of network event timings, so I'm worried showing this number here will be confusing or misleading. I updated the design to move this stat into the "Metrics" panel. Can you move this stat to the area highlighted in pink below. Ideally this stat can use the comparison to last test run feature.
