Most of the tests are not so flaky (~3% probability of failure) and there are plenty of non-flaky tests thus averaging total to 0% flakiness for the whole team and for each of the directories. I didn't verify this in detail yet, but it's a plausible explanation.

Also it may be somewhat confusing, but Flaky Failures shown for directories in https://chromiumdash.appspot.com/flakiness/input-dev are not the same as Flaky Failures shown for individual tests in https://test-results.appspot.com/flakiness/team/input-dev. Please hover the column titles to see the description and let me know if you intuition about these columns was different... then perhaps we should use something simpler, e.g. just summing the number of flakes of tests that happen in a given directory or whole team (for the first line).

I think it's too confusing for the two dashboards to show different data. I don't think we we gain much from the more complicated flakiness metrics in chromiumdash.

A simple sum of number of flakes seems like it would work well, be easily understood and match the numbers on test-results. Is that right?

Sure, will change that. Thanks for the feedback.

Removing ownership as I'm transitioning to another team and Sean is taking over the flakiness effort.
