Sorry for interrupting your conversation, but:
So, you've basically decided what needs to be included in the calculations, but you haven't yet come to a unanimous agreement on how to do it in the most rational way?
In my opinion, someone with authority needs to choose one of the options proposed here. Otherwise, this dispute will continue forever... because it is impossible to come up with a completely objective ranking that would take into account the interests of both the first and the second...
because your tournaments are not a major sport where all the rules are clearly defined.
Sincerely, chmo.
