Sometimes I have very elaborate test config which I want to reuse, but slightly change one thing (e.g. add one param to URL). I can easily re-run the test with exact same config, but it's not easy to slightly change config and re-run. You need to re-create the config from scratch by checking multiple checkboxes, and hoping you come up with same exact set of params as before
It's apparently possible to override medianMetric
param to tell WPT how to choose the median run.
It would be nice to use a custom metric for that (say the first perf entry marked with performance.mark('WptEndMetric')
).
Maybe it's already possible?

It has autocomplete=off
as a security measure (to prevent remembering sensitive data) which is probably the reason. Perhaps a browser extension could fix that?
