For example, someone seems to have been playing around with http://w3c-test.org/framework/details/i18n-html5/bidi-chrome-019, which messes up the result summaries.  I've seen several other instances of results I think need to be cleaned up, and made some mistakes myself. 

I think the sooner we can clean the test results the better. It will get harder as time goes on and the problems accumulate.
