I understand
As the ring gets closer to the top the gap needs to inclease. Just as NOS engines use larger ring gaps. That's not to say the second ring can't be gapped larger than the first. They both need to be opened up. No set rule on ring gaps except to gap them for the use they will get. I would go by the ring manufacturer's instructions.
