With all things, it is not necessarily unhelpful to turn the knobs to the max in both directions to see if the dent position in the middle is the best default or not. So Google's attempt at max sanitizing wasn't good which is kind of expected, but good to have the test results to prove. Going opposite to no safety put in place can also have an assumed outcome. That one however will be much more likely to have negative consequences if truly allowed to run.
