Yes, there could be a 'backbone' to PR decisions as THO said, then + the panel's discretion to root out any discrepancies.
The value of the numbers don't matter... only their value in relation to each other.
Anyway, there's various sets of formulas that would give a proper template for the panel to go by initially that actually take many key factors into consideration when creating a decent 'backbone' for the PRs.
Personally, I know of 2 methods that would work fine as well that haven't been mentioned yet, although possessing a few similar components to those mentioned already. Coming up with these systems isn't some long, vigorous process by any means like some put it up to be lol..
I don't know though..... I just don't understand fully why a mathematical system is even needed for brawl PR's (isn't it obvious who the best players are in the state anyway, as long as you have brackets(POST BRACKETS....)) and I also don't understand why some are so against having a system like this. The argument 'the process of making PRs is simple' could be used for either side at this point and the reasoning is getting a little moot...
I think the reason why people want a mathematical system is because the panel isn't 100% error proof. The panel may argue 'the possible errors made are very miniscule, why could that be reasoning for making such a system?' BUT... I don't think people are trying to discredit the panel, at all. Or at least I never have. I just know that it's a certainty that if one of these aforementioned systems(aforementioned in my post, not this thread) were used: less mistakes would happen, and even if there haven't been any mistakes, it would make less mistakes happen in the future. At this point, if I were a panelist, I would consider adopting it just so you wouldn't have to hear people talk about it anymore, lol.
As I said I don't think it's really necessary though. I just think every one should be a little more open-minded.
