That makes sense.  The time-skew issue is much less likely to occur for the unexpected failures tab.

There's still the issue of configurations that don't have bots, but IMHO we should just delete those configurations.  That's mostly what we've been doing (e.g., the google-chrome configuration is gone).  Do we have any left?

> re: "it's impossible to always know what the correct final configuration is" ... I don't quite understand this; assuming all the bots have produced results, and you know which bots are failing and which aren't, you can determine what the correct configuration is, right? So you're saying just one or both of those assumptions might not hold? or am I missing something?

You can never know for certain that all the bots have produced a consistent set of results because the bots aren't synchronized.  Ojan's point is that the time-skew issue is less likely to be a problem on the expected failures tab.  It's definitely a problem on the unexpected failures tab.
