I understand exactly what you've been trying to argue, but you need to understand that you cannot prove these hypotheticals. I hope that that concept is not over your head. You are trying to tell us that you know what would happen in imaginary games. You don't, so you have no argument. You can't debate with hypotheticals, only with facts.
In science, you test your hypotheses. Speculation is not the same as testing. Lol. The 900 minute game can not be tested. It will never be tested. A Chelsea-Barca 10 game series will never be tested. That will never happen. These are just hypotheticals, and hypotheticals can never win an argument. That's Debating 101.
You had me until your "refereeing" conclusion. FIFA should increase scoring first. Refereeing 22 guys is impossible for 1 guy (or even 3 counting linesmen).
