Review comment:
The value is -1 instead of 0 if it doesn't support output metrics, and as
you can see the error message in build, here the value is 0 instead of -1,
because the patch overwrites the value to 0 when the batch hasn't run. So yes
the last progress here is for "no data & no run", though the new commit should
fix this problem.
