I know the logf change is safe, I checked every value. But the search space for log is too large. I looked at the closest 1 billion values to both sides of 1.0, which are the critical ones. Everything checked out. I think at least on modern hardware everything is safe. If problems pop up due to old hardware we might have to conditionalize the changes.
