I’ve merged the above question into this topic, from an unnecessary new thread on the same general subject. Short follow-up questions don’t need a new topic, on the contrary, the context of the existing topic makes it a lot easier to usefully answer questions that could otherwise be very short and un-clear.
For completeness, I’ll quote the one reply of @H2CO3 from the other topic:
