I had to select 'request desktop site' as an option in the chrome browser, and not choose '4G' as my connection type (I chose DSL), to get the latency measurement to show up. The results are great though. http://www.dslreports.com/speedtest/355893 Download bloat (buffer in the cell site) is bad, but not absolutely horrible, at about 1.1 seconds. Upload direction is terrible - 5.8 seconds by the end of the test, and would probably have been higher given a longer test. I'm assuming that this buffer is in the modem in the handset, and is likely an almost infinite buffer.
