Inconsistency in Average total trace time

I see an inconsistency between the time averages between “Traceroute path” and “Average total trace time”.

For example: in my “Traceroute path” chart I have 4 hops:

  • Host: 0.00ms
  • Hop 1 (Gateway): 1.605ms
  • Hop 2: 51.00ms
  • Hop 3: 51.00ms
  • Hop 4: 45.00ms

The average of these times should be 45.00ms, but the “Average total trace time” field shows 796.35 ms.

Why does the time shown in the “Average total trace time” field not match the average of the hops observed in the “Traceroute path” graph?
