It seems I have misunderstood you in the last discussion.

in the last discussion [1] I tried to explain why I did not consider multiple
IOVs. In the reply to my answer [2] I seem to have understood that the current
implementation is fine.

So, shall I now implement the multiple IOVs approach outlined in [1]? If yes,
how many IOVs shall I consider?
