To be honest the speedtest on DSL reports has been broken for a while now and since it is a free site I doubt that the mods will ever get around to fix it. Its a known issues on the dsl froums.
1) OP's DSL Reports results show really high latency samples during uploads (Although most are less than 70 msec, two were 477 and 974 msec). That's really high, by any standard.
2) You're correct that the DSL Reports Speed Test is not the best test for bufferbloat. (It's a great first-cut, though.)
3) The researchers who defined bufferbloat use a tool called Flent (www.flent.org). This test is the very definition of measuring the increase in lag/latency during a test. It provides a repeatable test platform that allows you to create accurate graphs of the data, so it's easy to compare your results week to week or with others.
Flent is a bit tricky to set up, but definitely within the capabilities of the readers of this forum.

Do you have links/citations to the issue on the forums? I would like to pass this along to the author of the DSL Reports test. Thanks.
You can find your upload speed by running a est at speedtest.net
As for avoiding spikes, the XR500 QoS will eliminate them completely. Set Anti-Bufferbloat to ‘High Priority Traffic Detected’ and about 70% on both upload and download.
Then allocate bandwidth to your gaming devices on bandwidth allocation and you should be good to go!
Ok, great. Your upload bandwidth is obviously quite low, so Anti-Bufferbloat will really help in preventing lag spikes. If you have it at 70% and 'High Priority Traffic Detected', then you'll be preventing upload lag spikes.
