You might need to do some hacking to make sure it downloads the right coverage binaries, but you can probably do this by running measurer.py standalone and deleting (save them first) the old snapshots from the experiment.

I assume the clang cov one isn't finished yet?

[Shadoom7]

Yeah, still running, should finish today.
