Average and Current delay

I am new to PingPlotter and I have the following question.

After a few tests, I observed that often, the average and current round trip delays for a given number of hops are larger than the corresponding delays for larger number of hops.

This seems strange. A possible explanation I can give is that the numbers are obtained by different ping packets, but it still seems strange that the incosistency appears so frequently and for the same number of hops.

Is there something that I am missing?

The route length doesn't necessarily relate to the latency at the final destination. You can have a 15 hop route with 25ms of latency at the final destination, and a 5 hop route with 500ms of latency.

Even within a single target, intermediate hops might have higher latency than a hop further away. We talk about that here:
