What about the detail results for per ms cases?

[jdduke (slow), 2015/05/04 17:46:20]

Done.

Also can you add assertion for mean_frame_times to make sure that its value stay
the same after your patch.

[jdduke (slow), 2015/05/04 17:46:20]

Hmm, we already check timeline.ThreadMeanFrameTimeResultName(cc_thread). What
other assertion did you have in mind?
