Yes, I'd be fine with that, although the acceptable score could be
arguably different even across hw platforms, so we would have to pick a
conservative value to declare success/failure unless the test adapts
based on some heuristics. This said, I agree that running_on_vm() is our
friend to fully disable such check only on VM since the figure does not
make much sense there.
