Performance results with negative impact on some platforms should not be suppressed

I think that the following change to AMO's code will primarily hide issues with the measurements: A result where the measurement goes into negative is extremely unlikely if the measurement was performed correctly, currently such results are primarily caused by bug 648229. Also, if a fluctuation causes the baseline test to return a higher value this code will cause many add-ons to simply disappear from the map. If you don't want to accept negative numbers then use max(delta, 0), don't throw the result away.
To me it makes more sense not to show a failed test than show an incorrect result. An incorrect result would be more misleading IMO.

My suggestion is WONTFIX.

All the more reason not to suppress "strange" results. If you are certain that tests with negative results are always incorrect then it is a reason to rerun the test. At the very least the add-on should be marked with "performance test failed". If you simply suppress these results you will get into a situation again where issues like bug 648229 go unnoticed.
Testing errors should definitely be logged, and I don't have any problems on them being public somehow. However, I disagree that the patch should be backed out, which is what this bug is about.

What I asked for is a different handling of suspicious results - in its current form it is perfect for hiding bugs. And it did so at least once already.

Could we have AMO annotate the display with a "some tests failed" comment or something like that?
