Agreed very much. However, ping times can be used as latency determination metrics.
And latency is disproportionately important when you're concerned only with HTTP performance. However, pings *can* be used to measure bandwidth, by sending multiple sizes of ping and measuring the difference in response times between small and large pings. On a graph of ping size vs. response time, you'd see the y-intercept representing base latency and the slope representing bandwidth. This is how bing does its work. -- Shields, CrossLink.
